This thread is intended to provide a space for 'crazy' ideas. Ideas that spontaneously come to mind (and feel great), ideas you long wanted to tell but never found the place and time for and also for ideas you think should be obvious and simple - but nobody ever mentions them.

This thread itself is such an idea. Or rather the tangent of such an idea which I post below as a seed for this thread.

 

Rules for this thread:

  1. Each crazy idea goes into its own top level comment and may be commented there.
  2. Voting should be based primarily on how original the idea is.
  3. Meta discussion of the thread should go to the top level comment intended for that purpose. 

 


If this should become a regular thread I suggest the following :

  • Use "Crazy Ideas Thread" in the title.
  • Copy the rules.
  • Add the tag "crazy_idea".
  • Create a top-level comment saying 'Discussion of this thread goes here; all other top-level comments should be ideas or similar'
  • Add a second top-level comment with an initial crazy idea to start participation.

Socrates has some sound advice on making requests of powerful beings:

Our prayers should be for blessings in general, for God knows best what is good for us.

4polymathwannabe
The human way is not leaving things to be managed by the gods.
6eternal_neophyte
Indeed. But if you're going to appeal to an omniscient being, let them in their omniscience decide what's good for you.
3polymathwannabe
I'd feel dirty letting anyone, even a god, overwrite my terminal goals.
6Lumifer
That feeling of being dirty can be overwritten, too X-)
2eternal_neophyte
Has no human being ever overwritten your terminal goals?
0polymathwannabe
I have, a number of times. My parents tried, but at most were able to overrule them.
1eternal_neophyte
And it was always for the worse?
0polymathwannabe

Do you even have a terminal goal?

A god smart enough to know what's good for us is smart enough not to need a prayer to be summoned.
1James_Miller
The god might give great weight to individual preferences. I have tried to convince lots of people to sign up for cryonics. When I say something like "if it were free and you knew it would work would you sign up?" some people have said "no", or even "of course not." Plus, the god might have resource constrains and at the margin it could be a close call whether to bring me back, and my stating a desire to be brought back could tip the god to do so with probability high enough to justify the time I spent making the original comment.
2David_Bolin
For many people, 32 karma would also be sufficient benefit to justify the investment made in the comment.
-2hyporational
Our stated preferences are predictably limited and often untrue accounts what actually constitutes our well-being and our utility to those around us. I'm not sure I want to wake up to a god psychologically incompetent enough to revive people based on weighing wishes greatly. If there are resource constraints which I highly doubt it's especially important to make decisions based on reliable data. I think this much more likely reflects the dynamics of the discussion, the perceived unlikelihood of the hypothetical and the badness of death than actual preferences. If the hypothetical is improbable enough, changing your mind only has the cost of losing social status and whatever comforting lies you have learned to keep death off your mind and not much upside to talk about.
2ChristianKl
Consent seems to be an important ethical principle for many people and an FAI might well end up implementing it in some form.
0hyporational
True. Since people are so irrational, not to mention inconsistent and slow, it might be one of the most difficult problems of FAI. The whole concept of consent in the presence of a much more powerful mind seems pretty shaky.
0eternal_neophyte
I can easily imagine that if I ran a simulation of mankind's evolutionary history, I'd adopt a principle of responding to the requests of simulants given that they are small enough and won't interfere with the goals of the simulation, just in case they have some awareness. If the purpose of the simulation isn't simply to satisfy all the simulants' needs for them (and would in fact be orthogonal to its actual purpose), they would have to make some kind of request for me to do something.

True, but the interesting question is whether you want to summon a genie of uncertain benevolence.

I wouldn't summon a genie of uncertain benevolence. But if one already exists it might be worth asking it for a favor. Most unfriendly genies would ignore my wishes. The question is, do you want to draw the attention of a genie of uncertain benevolence that is influenced by your explicit requests to it?

2aausch
Thanks! Presumably, an omniscient being will be able to derive a "bring everyone back" goal from having read this sentence.

How conscious are our models of other people? For example; in dreams it seems like I am talking and interacting with other people. Their behavior is sometimes surprising and unpredictable. They use language, express emotion, appear to have goals, etc. It could just be that I, being less conscious, see dream-people as being more conscious than in reality.

I can somewhat predict what other people in the real world will do or say, including what they might say about experiencing consciousness.

Authors can create realistic characters, plan their actions and internal thoughts, and explore the logical (or illogical) results. My guess is that the more intelligent/introspective an author is, the closer the characters floating around in his or her mind are to being conscious.

Many religions encourage people to have a personal relationship with a supernatural entity which involves modeling the supernatural agency as an (anthropomorphic) being, which partially instantiates a maybe-conscious being in their minds...

Maybe imaginary friends are real.

Since this is a crazy ideas thread, I'll tag on the following thought. If you believe that in the future, if we are able to make ems, and we should include them in our moral calculus, should we also be careful not to imagine people in bad situations? Since by doing so, we may be making a very low-level simulation in our own mind of that person, that may or may not have some consciousness. If you don't believe that is the case now, how does that scale, if we start augmenting our minds with ever-more-powerful computer interfaces. Is there ever a point where it becomes immoral just to think of something?

8Pentashagon
God kind of ran into the same problem. "What if The Universe? Oh, whoops, intelligent life, can't just forget about that now, can I? What a mess... I guess I better plan some amazing future utility for those poor guys to balance all that shit out... It has to be an infinite future? With their little meat bodies how is that going to work? Man, I am never going to think about things again. Hey, that's a catchy word for intelligent meat agents." So, in short, if we ever start thinking truly immoral things, we just need to out-moral them with longer, better thoughts. Forgetting about our mental creations is probably the most immoral thing we could do.
6Lumifer
In e.g. Christianity it's immoral to think of a lot of things :-/
2Val
Not exactly. If I ask you "what if you robbed a bank?" you will think of robbing a bank, you actually cannot prevent yourself from thinking about robbing a bank. And yes, you just lost the Game. What makes such a "thinking of a lot of things" immoral is not the thinking itself, but whether it is coupled with a desire.
3Lumifer
But you think you can prevent desire from sneaking into your thinking about sinful things..? ;-)
1Irgy
In the interest of steel-manning the Christian view; there's a difference between thinking briefly and abstractly of the idea of something and indulging in fantasy about it. If you spend hours imagining the feel of the gun in your hand, the sound of the money sliding smoothly into the bag, the power and control, the danger and excitement, it would be fair to say that there's a point where you could have made the choice to stop.
1Lumifer
Yes, of course, there is a whole range of, let's say, involvement in these thoughts. But if I understand mainstream Catholicism correctly, even a brief lustful glance at the neighbor's wife is a sin. Granted, a lesser sin than constructing a whole porn movie in your head, but still a sin.
1VoiceOfRa
Yes, and in Yudkowskian rationality, lying to oneself is a sin. What's wrong with having a conception of sin that includes thoughts?
0Irgy
Well that's why I called it steel-manning, I can't promise anything about the reasonableness of the common interpretation.
-1ChristianKl
That depends on how strongly a person is suggestible.
1Val
It doesn't. Just by parsing that sentence, if you understood it, it means you though of it.
-3ChristianKl
No, it's quite possible to parse the sentence without actually going along with it. Just because you can't doesn't mean that other people can't.
1Val
In this case we should define "going along" and "thinking of", because otherwise this will be just empty arguing about semantics. My point was that parsing and understanding that sentence means you are thinking of it, even if for just a short moment, and that it is different from actually having even the slightest desire to actually do it. Where does your definition of "going along" fit into it?
0qvalq
You worded this badly, but I agree.  It is possible to read "you robbed a bank" without imagining robbing a bank. Just very hard, and maybe impossible if you're not readied.
4James_Miller
So George R. R. Martin is a very evil man.

"A tulpa could be described as an imaginary friend that has its own thoughts and emotions, and that you can interact with. You could think of them as hallucinations that can think and act on their own." https://www.reddit.com/r/tulpas/

2Pentashagon
The reason I posted originally was thinking about how some Protestant sects instruct people to "let Jesus into your heart to live inside you" or similar. So implementing a deity via distributed tulpas is...not impossible. If that distributed-tulpa can reproduce into new humans, it becomes almost immortal. If it has access to most people's minds, it is almost omniscient. Attributing power to it and doing what it says gives it some form of omnipotence relative to humans.
8NancyLebovitz
Some authors say that their characters will resist plot elements they (the characters) don't like.

Some would say that this is their imagination.

0Pentashagon
I resist plot elements that my empathy doesn't like, to the point that I will imagine alternate endings to particularly unfortunate stories.
0[anonymous]
This does not weird me out. They use parts of their brain to simulate characters brains. They use another part of their brain to write a plot they themselves like. Why should the simulated character necessarily like it? If they have good simulation skills - and if not they will never write memorable characters - this is perfectly expected...
7medlcld
What exactly does "consciousness" even mean here, though? I've written before, and at my best my model of my characters included: * Complex emotions (as in multiple emotions at once with varying intensities) * Intelligent behavior (by borrowing my own intelligence, my characters could react intelligently to the same range of situations as I can) * Preferences (they liked/disliked, loved/hated, desired/feared, etc) * Self-awareness (a well-written character's model includes a model of itself, and can do introspection using the intelligent behavior above) What else is necessary to have consciousness? There are plenty of other things that could be important, but they don't seem necessary to me upon reflection. For example: * Continuity of self; Time skips in stories involve coming up with approximately what happens over a period of time, and simply updating the character model based on the expected results of that. But if it turned out that significant parts of my life were skipped and fake memories of them were added, I would still value myself for the moments that weren't skipped over, so I don't think this is necessary for consciousness. * Independence; I can technically make a character do whatever I want, but that often breaks their characterization, and if someone was a god and could make me think or do anything, I'd want to get free, but I would still value myself. * Consistency; At my best my characters are mostly consistent in characterization, but I'm not often at my best. But mood swings and forgetting things happens to real people too, so I don't think it's a deal-breaker on consciousness. * Subconscious; A really good author almost certainly uses their own subconscious to model the character and their behavior, so it's not clear that a character doesn't have a subconscious. It's not quite the same as a real person's, but as long as it still results in the big 4 at the top I don't think this matters much. * Advanced senses; Visualization

This is a great blog post on a similar idea: http://www.meltingasphalt.com/neurons-gone-wild/

Ban music in political campaign advertisements. Music has no logical or factual content, and only adds emotional bias.

Here's an example of an ad with music intended to give two different emotional tones (optimistic/patriotic in the first six seconds, then sinister in the rest).

8Dagon
Why only in political ads? Product consumption and lifestyle choices have orders of magnitude more impact on most people's lives than political choices, why not start by banning manipulative messaging there?
4michaelkeenan
My thinking with that - not that I've thought about it very hard or actually endorse this beyond "interesting crazy idea" - was that one's emotions about a product can genuinely affect one's enjoyment of it. Maybe a certain food or other product is designed to evoke a cowboy's frontier life, or an archetypal grandmother's cooking, or something like that. Music would help create that association. Overall the effect might still be pernicious but I'm not sure about that.
4Dagon
I'd argue that emotions about politics genuinely affect one's enjoyment of government as much, if not more so, than any other product. Why don't you want us to be happy?
8michaelkeenan
Fair enough. My thinking is that voting has severe effects on others, while one's choice of consumer product mostly affects oneself. Maybe a particular well-marketed beer can make one feel strong and virile; a well-marketed approach to foreign policy might do the same, but with worse consequences for others.

To learn about the genetic and environmental basis of intelligence study children who have significantly higher IQs than either of their biological parents.

First step in the study: paternity tests for the potential subjects.

3knb
Child IQ scores tend to regress toward the mean as they get older.
3qvalq
Adult IQ scores do too, I think.
1eternal_neophyte
Perhaps this means students shouldn't be excluded from advanced classes on the basis of IQ, but rather on the basis of being less willing to try.
0passive_fist
Why do you think this would be better than also studying children with lower IQs than their parents? I'm curious to know your reasoning.
7drethelin
There are a lot more ways something can be messed up than improved.
8gwern
Yeah. If all you want is mutations which decrease IQ, well, studies of the profoundly retarded have turned up dozens, perhaps hundreds or thousands by now, confirming what everyone guessed in the first place (that the retarded had genetic problems which broke all sorts of biological systems, which intelligence is downstream of). But these findings have yet to lead to any breakthroughs in understanding the biology of intelligence that I've heard of. (This reminds me a little of the paper "Can a Biologist Fix a Radio? — or, What I Learned while Studying Apoptosis".)

Use computers to discover the Theory of Everything.

(I am not a physicist, so what I say here is probably wrong or confused, but I am saying it anyway, so at least someone could explain me where exactly am I wrong. Or maybe someone can improve the idea to make it workable.)

As far as I know, (1) we assume that the laws of the universe are simple, (2) we already have equations for relativity, and (3) we already have equations for quantum physics. However, we don't yet have equations for relativistic quantum physics. We also have (4) data about chemical properties of atoms, that is, about electron orbitals. I assume that for large enough atoms, relativistic effects influence the chemical properties of the atoms.

The plan is the following: Let the computer explore different sets of equations that are supposed to represent laws of physics. That is, take a set of equations, calculate what would be the chemical properties of atoms according to these equations, and compare with known data. Output those sets of equations that seem to fit. Create a smart generator for sets of equations, that would generate random simple equations, or iterate through the equation space starting with the simplest ones. Then apply a lot of computing power and see what happens.

5Viliam
Thanks! I will savor the warm feeling that I generated an idea in a field I didn't study that the people who study the field also consider hopeful. :D Okay, if someone understands the topic, could you please tell me what exactly is the problem; why this wasn't already solved? -- Is the space of realistically simple equations still too large? Is it a mathematical problem to predict the chemical properties from the equations? Are we missing sufficiently precise data about the chemical properties of large atoms? Are the relativistic effects even for large atoms too small? Is there so much noise that you can actually generate too many different sets of equations fitting the data, with no quick way to filter out the more hopeful ones? All of the above? Something else?
7leplen
Noise is certainly a problem, but the biggest problem for any sort of atomic modelling is that you quickly run into an n-body problem. Each one of of n electrons in an atom interacts with every other electron in that atom and so to describe the behavior of each electron you end up with a set of 70 something coupled differential equations. As a consequence, even if you just want a good approximation of the wavefunction, you have to search through a 3n dimensional Hilbert space and even with a preponderance of good experimental data there's not really a good way to get around the curse of dimensionality.
0[anonymous]
Am I understanding the relevance of the curse of dimensionality to this correctly: Generally, our goal is to find a simple pattern in some high-dimensional data. However, due to the high dimensionality there are exponentially many possible data points and, practically, we can only observe a very small fraction of that, so curse is that we are often left with an immense list of candidates for the true pattern. All we can do is to limit this list of candidates with certain heuristic priors, for example that the true pattern is a smooth, compact manifold (that worked well e.g. for relativity and machine learning, but for example quantum mechanics looks more like that the true pattern is not smooth but consists of individual particles).
4leplen
The true pattern (i.e. the many-particle wavefunction) is smooth. The issue is that the pattern depends on the positions of every electron in the atom. The variational principle gives us a measure of the goodness of the wavefunction, but it doesn't give us a way to find consistent sets of positions. We have to rely on numerical methods to find self-consistent solutions for the set of differential equations, but it's ludicrously expensive to try to sample the solution space given the dimensionality of that space. It's really difficult to solve large systems of coupled differential equations. You run into different issues depending on how you attempt to solve them. For most machine-learning type approaches, those issues manifest themselves via the curse of dimensionality.
1passive_fist
I fail to see how this would be qualitatively different from how physics has always been done. We've always been using computers to generate new laws to fit observations, except in the past those computers have been our brains, and in the past half-century they've increasingly been our brains augmented with artificial computing machines. Our current lack of progress in physics doesn't stem from lack of ideas, or even lack of ability to come up with theoretical predictions. We have plenty of ideas. Our lack of progress stems from lack of experimental data. We have a large number of competing explanations and they all work in the same in the infrared limit (physicist-speak for 'everyday low-energy conditions') but they have subtle differences in the high-energy limit. Our two main routes to physical evidence have been particle physics measurements and cosmological data. We are not yet able to probe to high enough energies in particle physics to sort out the various theories, and we have far too many uncertainties in cosmological data to substantially help us out. Maybe better AI in the future will help us with this, but it would have to be incredibly powerful AI.
2Douglas_Knight
What are you talking about? I don't think that's true at all. Added: I suppose the parameters of the standard model are subtle difference in the high energy domain, but I don't think that's what you mean.
9leplen
I really like this topic, and I'm really glad you brought it up; it probably even deserves its own post. There are definitely some people who are trying this, or similar approaches. I'm pretty sure it's one of the end goals of Stephen Wolfram's "New Kind of Science" and the idea of high-throughput searching of data for latent mathematical structure is definitely in vogue in several sub-branches of physics. With that being said, while the idea has caught people's interest, it's far from obvious that it will work. There are a number of difficulties and open questions, both with the general method and the specific instance you outline. It's not clear that this is a good assumption, and it's not totally clear what exactly it means. There are a couple of difficulties: a.) We know that the universe exhibits regular structure on some length and time scales, but that's almost certainly a necessary condition for the evolution of complex life, and the anthropic principle makes that very weak evidence that the universe exhibits similar regular structure on all length/time/energy scales. While clever arguments based on the anthropic principle are typically profoundly unsatisfying, the larger point is that we don't know that the universe is entirely regular/mathematical/computable and it's not clear that we have strong evidence to believe it is. As an example, we know that a vanishingly small percentage of real numbers are computable; since there is no known mechanism restricting physical constants to computable numbers, it seems eminently possible that the values taken by physical constants such as the gravitational constant are not computable. b.) It's also not really clear what it means to say the laws of physics are simple. Simplicity is a somewhat complicated concept. We typically talk about simplicity in terms of Occam's razor and/or various mathematical descriptions of it such as message length and Kolmorogov complexity. We typically say that complexity is related to
8Douglas_Knight
No, it is not believed that gravity has a measurable effect on chemistry. People have pretty much no idea what kind of experiments would be relevant to quantum gravity. Moreover, the predictions that QFT makes about chemistry are too hard. I don't think it is possible with current computers to compute the spectrum of helium, let alone lithium. A quantum computer could do this, though.
0[anonymous]
I'm by no means a physicist, but isn't special relativity, which is related to gravity/spacetime, able to cause magnetism? Couldn't that account for a chemical effect?
6Douglas_Knight
Yes, special relativity is very important. Indeed, I was speaking of QED, a quantum mechanical model that incorporates special relativity.
5Houshalter
You'll probably be interested in reading this: http://www.wired.com/2009/04/newtonai/ and this: http://www.radiolab.org/story/91712-limits-of-science/ The program described, Eureqa, is available online and had a free trial. I have spent a lot of time playing with it and trying it on different problems and datasets. I don't think it could learn a theory of everything with out a lot of human help to reduce some parts of the problem. E.g. "here are a few numbers as inputs, here is a number as an output. Fit it out only using basic mathematical functions." But its a start.
5Kyre
Nitpick: we have equations for (special) relativistic quantum physics. Dirac was one of the pioneers, and the Standard Model for instance is a relativistic quantum field theory. I presume you mean general relativity (gravity) and quantum mechanics that is the problem. In the spirit of what Viliam suggested, maybe you could do computational searches for tractable approximations to QFT for chemistry i.e. automatically find things like density functional theory. A problem there might be that you do not get any insight from the result, and you might end up overfitting.

A crazy prediction: 25 years from now, what we call intermittent fasting will be called a normal daily schedule, and what we call a normal daily schedule (3 meals and some healthier snacks) will be called food addiction. And the primary reason for this change will not be even e.g. obesity but the mental effects: people will consider it an obvious truth that being constantly in a fed state dulls the mind and saps motivation and generates akrasia and generally harms productivity.

They will look back to us and think these people went through life half-asleep because they went through life constantly (nearly) sated.

They will says stuff like "you are a like a dolphin: if you feed yourself before you jumped through all the hoops you planned for that day, you won't jump through them".

Arriving to work with a breakfast in hand will be a bit like arriving to work with a beer in hand: if you roll best that way it is not for others to judge, but most people will prefer to work sober and sharp - and that means literally staying hungry. Today we joke about having a food coma and difficulty to concentrate after a work lunch, fixing ourselves up with coffee: this will sound a lot like as an 1950's person complaining that he finds it hard to concentrate after a two-martini lunch sounds today.

Mental effects of IF seem so easily measured and carried out by a self-experimenter that there's no need to speculate about it, you should just do it. Thus far, I haven't heard of any human trials examining the cognitive effects.

I have been doing intermittent fasting for a few years, and while I think it has probably helped my mental performance, the effect isn't all that strong. If intermittent fasting becomes commonplace it's more likely, I predict, because of its anti-aging effects.

There is a transition period. After doing IF for a few months you might be fine in the mornings without breakfast. Your caveman ancestors certainly didn't need breakfast before they went out hunting.

Same. I'm completely fine if I skip lunch though. I think I might try doing that regularly and see how it goes.

In my experience, skipping dinner works better.

Sleeping hungry? Sounds impossible to me. Working with a grumbling stomach is for me totally logical: hunger is a motivation to go out and hunt and it can be channeled into other activities. But how could one sleep without feeling sated? I mean, wouldn't that be the normal routine of an animal: be hungry, go hunt, feel sated, sleep?
6Lumifer
No, because sleep is tied to the diurnal cycle and the success of a hunt (for carnivores) cannot be so conveniently arranged.
0[anonymous]
Is it? Domesticated dogs derive from a nocturnal species, when born feral they are nocturnal, but have no problems being diurnal when raised so by humans. Humans can easily adapt to two shorter sleeps or even the weird polyphasic routine. OTOH "food coma" is a thing.
3Lumifer
Not sure this is true. In the tropics (where there are a lot of feral dogs) the peaks of activity for most everyone is dawn and dusk, avoiding the midday heat. As far as I know nocturnal predators certainly exist but are rare. Don't know about that either. Humans can adapt. Some humans can easily adapt. A lot can't.

Wasn't the idea to not be sated until the end of the day and thus have a clearer head and be more productive? I'm not concerned about losing weight, which I have heard skipping dinner is pretty good for.

Could be but bulletproof is really the 100th fad diet invented and somehow neither has a control group who is not a McD junkie but lives on basic standard traditional more-or-less Western "grandma type" homecooked food. Roast chicken, mashed potatoes type food. That would be a useful control group to have. I must say, eat nothing for X hours can also be a fad diet but it is refreshingly different and does not require difficult and complicated things to do. One of these days we should discuss the meta of diets here. Are paleo/keto/bulletproof/vegaan/anything primarily aimed at people who have a high control over their diet? For example they live in a Western country but it totally happened with them that they bought a Korean cookbook and tried cooking something from it, they knew where to get ingredients, they were curious about trying things, was it like that? Just because most people I know are running halfway on hand-me-down family recipes in autopilot mode and they buy the other half from some takeaway.

If we lived as ems in a simulated universe, literally any claim of any religion of any religion could be true. Any other claim, too.

The point is, when people seriously ponder if we lived in a simulated universe but have nothing but scorn for religions, it is not so much rational as cultural. In a sci-fi geek subculture, simulation is cool, religions not.

Culture, in this sense, means the following. If theory A and B makes the same predictions but the formulation, the wording of A seems vastly preferable than B - that is culture.

IMHO this is one of the most important kind of bias in me I need to control for. I need to ask myself "if this was reworded in a way that is culturally compatible with me, would I still reject it so strongly?" or the opposite "is it something entirely without merit, but merely worded in a way that presses my 'cool' buttons?"

3DanArmak
If we live in a non-simulated universe, (almost) any claim of any religion can still be true. It's just so astronomically unlikely that we shouldn't spend any time considering it. (See: Pascal's Wager.) How are ems different? A uniform prior over all possible religions isn't useful. What evidence would they have, from the mere fact of being in a simulation, that any particular set of religious claims is likely, aside from the bare claim "there are Simulators but we don't know anything about them except that they want our universe to be simulated"?
6[anonymous]
I think a step from a lawful universe to an arbitrarily programmable universe would be fairly big. We exclude miracles in principle, for ems, miracles would be possible. If ems would agree the universe has a Programmer who is allmighty (can simulate what he wants), omniscient (can look at any part of the source code) it would be a big step. So it would be relevant to the meta step "are miracles possible?" and not to the more object level step "is this X miracle report for reals?" Also a uniform prior would be useful for the more syncretic approaches - it would not be so useful for primitive kind of religious approaches like "thing X is written in my holy book while some other holy books writes something totally different" but it would be more useful for the kind of "unified theology/philosophy" that the best minds in Islam (Avicenna) Judaism (Maimonides) Catholicism (Aquinas) were developing. My point is not the veracity of each religious claim but the veracity of living in a kind of universe where religious claims are possible, even likely that something like those happens (the Programmer plays around with stuff, tests ideas, throws a bunch of tablets on a desert tribe to experimentally test some sociology theories of ems) and then all we had to decide is which ones.
4Viliam
Essentially, you assume here that the distribution of "universes someone bothers to simulate" is different from the Solomonoff priors in a way that makes universes where religion is true more likely. May be. If the simulators are humans, some of them would enjoy playing gods; and even if it is a small minority, it would still be a larger fraction than universes where gods "naturally" exist as complicated laws of physics. If the simulators are alien intelligences... well, I would be less certain about those, but still seems like the fraction of situations where the simulator decides to personally interact with the simulation should be larger than universes where an intelligence is "hardcoded" into laws of physics. But there would still be many simulated universes where the simulator is not interested in interaction with sentient beings, and all religions arise naturally for reasons unrelated to their correctness. Or the simulator would interact with the world, but in a manner totally different from what religions talk about; imagine for example that our world is just a computer game played by a bored teenager who once in a few millions of years clicks a mouse button to drop a huge meteor and change ecosystem; the individual humans are too small and short-lived for him to even notice. Maybe the simulator completely ignores humans, and is only using this universe as an incubator for an AGI that he will later ask to compute some mathematical problem. So, the probability of some religion being true could be greater, but still relatively small. Not sure if large enough to excuse Pascal's wager.
3jacob_cannell
Across the multiverse, some universes support life, and some of those features civs which create lots of sims. Given that our physics seems to support enormous numbers of sim universes per basement universe, most of the copies of ourselves are probably in sims. Realizing that, there is a general convergent strategy that we should precommit to: in the future when we have the power we should 'win the sims arms race' so to speak and create many sims of our past. In this way we ensure that our sim is benevolent. These kinds of game-theoretic convergent considerations deeply effect the distribution over sim scenarios, and they do suggest what kinds of religious/metaphysical theories are more or less likely to be true. General resurrection - as in the book religions (zoraster/judaic/christian/islam), is a high likelihood cluster, as it naturally falls out of the whole use future sim power to defeat death strategy mentioned earlier. Basically, we want the god above to be aligned to our values, and we can best achieve this by expending sim power in the future.

Suppose backward time travel is possible. If so, it's probably of the variety where you can't change the past (i.e. Novikov self-consistent), because that's mathematically simpler than time travel which can modify the past. In almost all universes where people develop time travel, they'll counterfactualize themselves by deliberately or accidentally altering the past, i.e. they'll "cause" their universe-instance to not exist in the first place, because that universe would be inconsistent if it existed. Therefore in most universes that allow time travel and actually exist, almost all civilizations will fail to develop time travel, which might happen because those civilizations die out before they become sufficiently technologically advanced.

Perhaps this is the Great Filter. It would look like the Great Filter is nuclear war or disease or whatever, but actually time-consistency anthropics are "acausing" those things.

This assumes that either most civilizations would discover time travel before strong AI (in the absence of anthropic effects), or strong AI does not rapidly lead to a singleton. Otherwise, the resulting singleton would probably recognize that trying to ... (read more)

6Douglas_Knight
Since quantum mechanics is true, Deutsch self-consistency has pretty big advantages over Novikov self-consistency.
0D_Malik
Good point. I may be thinking about this wrong, but I think Deutsch self-consistent time travel would still vastly concentrate measure in universes where time travel isn't invented, because unless the measures are exactly correct then the universe is inconsistent. Whereas Novikov self-consistent time travel makes all universes with paradoxes inconsistent, Deutsch self-consistent time travel merely makes the vast majority of them inconsistent. It's a bit like quantum suicide: creating temporal paradoxes seems to work because it concentrates your measure in universes where it does work, but it also vastly reduces your total measure.
2Douglas_Knight
That's why it's not usually called "Deutsch self-consistency." It's not supposed to be a filter on legal universes, but a dynamic rule that each initial condition does lead to a consistent universe. The resolution of the grandfather paradox is a 50-50 superposition of the universe where you are born and leave and the universe where you appear, kill your grandfather, and are never born. You could say that it filters out the 80-20 superposition, but that's like saying that Newton's self-consistency principle filters out universes that don't obey his laws. (Well, maybe that's Lagrange's self-consistency principle...)
0[anonymous]
I'm not sure that comparison works. I can pick any initial universe-configuration and time-evolve it under Newtonian gravitation; a solution will always exist. But if I time-evolve initial conditions under laws that allow backwards time travel, it's not clear to me that there necessarily exist any solutions. Maybe the Deutsch law forces the superposition to be 50-50, but the other physical laws force it to be 80-20. It may be that the Deutsch law is just a logical consequence of the other physical laws, in which case I think you'd be right. (This all with the caveat that I don't really know physics, so I'm likely completely wrong.) I can't really think about this without having some idea of how it's chosen which universes are real.
6John_Maxwell
One thing I've never seen people mention re: time travel is that if you travel back in time six months, say, you'll find yourself floating out in space with the Earth on the other side of the Sun. (The Sun is in a slow orbit around the Milky Way, which itself is moving, right?) So practical time travel also requires practical space travel?
8Viliam
What exactly determines where you will appear in the past? Because there is no absolute reference frame, so... Those who say "on the other side of the Sun" assume that time travel follows the position of the Sun. Well, why Sun? Why not the center of the galaxy? Why not Earth? Given these three options, Earth reference frame feels most logical to me... the intuition is, it is the gravity of Earth that impacts me most, and in the absence of absolute reference frame, the time travel should track the gravity lines instead. Problem is, I am not a satellite orbiting Earth. I am standing on the ground, which limits my movement as the gravity of the Earth would want it to be. Should the time travel also take this into account? Sounds wrong: then it should track all interactions of my body with everything, including the air I would be passing through... does not make sense. So if I change my model into "time travel converts my body into a point-with-mass and then tracks the gravity lines", travelling in time backwards should move me up -- into such height that I will drop to the ground during the time interval. Under this model, travelling six months in the past would move me to a place in a space, difficult to calculate precisely (chaos theory, etc.), where if I start freely falling, in exactly six months I would drop on the ground approximately on the place where the time travel started (but not exactly there, because of friction and other interactions). Sounds similar in effect, but it's not the same.
2[anonymous]
I have a whiff of this type of literary time travel being supernatural i.e irreducibly mental: the closest model is replaying a memory differently this time: a mental thing.
2NancyLebovitz
Charles Williams' Many Dimensions has time travel as moving your sense of the present along your time line.
5Gram_Stone
That seems like a magical sort of time travel; the sort that is conceivable but unphysical; a garbage in, garbage out type-deal. I'd echo Viliam's remark on no absolute reference frames. I think it helps to imagine how you might actually, physically perform time travel. I usually see it suggested that one create a wormhole and accelerate one of the mouths. Time dilation will cause an observer in the reference frame of the accelerated mouth to experience less subjective time. Travel through the stationary mouth, and you'll apparently come out of the accelerated mouth at an earlier moment in time. No magic involved.
4Douglas_Knight
Any system of time travel in which the traveler does not teleport through time, but instead traverses all intervening time somewhat addresses this. There is an implication that the vessel is held near the Earth by the same gravity that would have held it in place ordinarily. In particular, this was true in Wells's original story. I think that the film Primer addresses this explicitly.
2westward
Slow orbit? More like 120 miles per second in reference to the galactic center. Charlie Stross's Eschaton books have a pretty good take on time travelling, light cones, and causality.
1Gurkenglas
Some civilization would have thought of that and made sure to direct their research away from time travel and towards AI.
0Yosarian2
Alternately, if a type time travel is invented where you can change the past, you would expect people to keep meddling with the past until they accidentally changed it so much that time travel had never been invented. This process would continue, over and over again, and the final results is that the final "stable" timeline will be one where time travel is never invented; not because it's not possible, but simply because every timeline where time travel is invented eventually changes it's own past until it no longer has time travel.

Greece lacks money, but they do have a whole lot of reasonably large, quite beautiful islands they barely use (only a small fraction of the 1200 islands are significantly inhabited) but which have the ideal Mediterranean climate for human habitation. Selling off sovereignty over these islands to other countries or to new country projects would be a great way to get some quick cash and there might be some downstream benefits, like increased trade in the region.

I think you vastly underestimate the power of nationalism. Greece is especially vulnerable to nationalism due to a glorious ancient past and really long Ottoman occupation. Still I think any government who accepted that would be toppled by nationalists.

If you sell land, it's probably lost forever. If you sell land which was once part of your sovereign territory, you will have no claim over it (in contrast to a land which was taken from you by force). One doesn't have to be a caricature of an ultra-nationalist to dislike the idea of losing something permanently to cure a temporary problem. What about leasing it instead?

Years ago I jokingly suggested to sell Crete to Turkey, in exchange for taking over Greece's debt (no doubt Turkey would jump at the opportunity and bend over to do anything possible to meet the debt payment criteria). The reactions I got were predictable, in the vein of "hell would freeze one hundred times over before this happens". Jokes aside, selling territory (with actual sovereignty transfer, as opposed to simple real estate acquisition) seems to be a bit of no-go in the last decades. Especially selling it under duress for economical reasons.

Selling territory is already impossible politically, but what's much worse is selling over a population of your citizens, or forcing them to relocate. An uninhabited island would be an easier sell, but also of much less value to anyone.

Fusion energy from... hydrogen bombs. Is there a way? Maybe underground explosions with water pumped in, turning to high-pressure steam, and powering a turbine?

This is actually a topic I'm fairly well-read on.

The basic problem is that hydrogen bombs are powerful. To make this idea economically competitive, you need very large bombs, as smaller bombs derive a proportionally higher amount of their energy from fission, and fission fuel (especially the high-quality fission fuel needed for a warhead) is very expensive. The problem, of course, is that with such powerful bombs (hundreds of kt range), there's just no way to safely confine the effect of the shock waves AND produce useful power at the same time.

So project PACER (as SIlentCal linked) was designed to use smaller, more-containable weapons. But here you have the problem that since the bombs are small, they're mostly fission, and the produced power winds up being about 3x more expensive than a conventional nuclear power plant.

Unless someone figures out a way to make a small all-fusion bomb, this idea is never going to be feasible.

9SilentCal
Not so crazy https://en.wikipedia.org/wiki/Project_PACER
4Thomas
The best way of doing this, is to have a big steel hollow sphere with vacuum inside. A detonation of a hydrogen bomb in the center would warm the sphere and some steam engines on the outside could harness this power. The problem is, that the vacuum should be very high and the sphere quite large, so the outside pressure is an important factor. So you should place this gadget into orbit, where the cooling is not very simple. Nor the electricity transport back to Earth. Otherwise, it's a good solution. This way we could have had fusion electricity some time ago. Perhaps with small hydrogen bombs a.k.a. neutron bombs. Otherwise those steel spheres would have to be too big to be stable on Earth.
2passive_fist
The sphere would need to be extremely large to be able to absorb the energy of a nuclear weapon without being blown apart. Most of the radiated energy (being of the form of soft x-rays and UV) is going to be absorbed in the first cm or so of material. Assuming you use iron (a good choice as iron is plentiful), the limit is around the 100 kJ/m^2 range, which means that for a 100 kiloton (418 terajoule) nuclear weapon your shell would have to have a surface area on the order of 4.18 billion m^2, or a radius of 31 km. Assuming you could design an ultra-material with one MJ/m^2 absorption ability, it's 10 km, but then you'd have to overcome problems of ablation and spalling. You could get by with a smaller nuke and maybe reduce to < 1km, but the nukes would be so expensive it would be much cheaper to just use solar power at that point.
-1Thomas
Nukes not need to be too expensive. A mass production would bring their price down. Still, big empty spheres would pose a problem. Perhaps we should put them on the top of a 20 kilometers high tower and cool them with the water pumped up. An explosion of 1 Mt every hour would mean about 1000 GW of raw power. Several of those would be currently more than enough.
1passive_fist
Mass production wouldn't necessarily make them less expensive than they already are. During the cold war the USA and USSR effectively mass-produced thousands of warheads. Official cost estimates for the manufacture cost aren't available but it seems that the US government managed to bring the cost of plutonium down from about $100,000/g to $500/g or so (The price of plutonium for civilians using it for chemistry purposes is currently around ten times that, however, and it's obviously an extremely restricted and regulated substance). A nuclear weapon needs about 2 kg of plutonium minimum, so that's about $1,000,000 per warhead at the very least.
0Thomas
It's a bargain. Even one billion US$ per day for the bombs, would be like nothing. We are talking about the energy output comparable with all the others (coal, oil, gas, nuclear, hydro ...) combined!
3passive_fist
Not necessarily. Plutonium has about 90 TJ/kg energy density. At $500/g, that comes out to about 180 MJ/$, or 2 c/kWh. That's only a bit below half of coal's 4.63 c/kWh. And this is only for the fuel! If you were to go the all-plutonium route, it would probably wind up being more expensive than coal. High-yield fusion would be another matter.

You have to have fusion. With fision you have to clean too much. And the OP wanted the fusion as well.

Project Daedalus has the same basic concept. It's a very interesting topic to research and might give you some insight on this topic.

A large-scale social experiment in the form of a MMOG to recreate dynamics of feudalism, possibly intensified by being bet upon.

  • There are a fixed number of castles in the game. Each castle has one owner at a given time.
  • A castle provides a steady income to its owner. This is the only source of in-game money.
  • A group of players can jointly attack a castle. If they defeat the current owner and any allied players in in-game combat, a pre-specified member of the attackers becomes the new owner.
  • The game does not provide contract enforcement mechanisms. You can recruit an attacking army by promising them a share of the castle's income, but they only have your word you'll follow through.
  • (optional) A monthly payout is distributed in proportion to in-game wealth. If the game were widely played, and wealth were highly concentrated, this could be very significant for some. Failing this, soft messaging such as leaderboards encourages amassing wealth as a goal.

The idea would be to see the coalition dynamics that play out. My suspicion is that people would at first try egalitarian coalitions to share income evenly, but over time things would get more and more hierarchical as established coalitions started admitting 'junior partners' on worse terms.

EVE already works sufficiently like that.

2SilentCal
Interesting, never played it. What's the typical structure of dominant alliances?

"The best way to describe running an Eve alliance is like being a CEO of a major multinational company, except nobody gets paid but a shit ton of work still has to get done." :-)

Basically it's weakly hierarchical -- you can't really compel anyone to do anything, but you can set up a system of incentives to persuade people to do what you want. Don't think there's much egalitarianism because a corp needs to function effectively and direct democracy does not scale.

If humanity did this, at least some of us would still want to spread out in the real universe, for instance to help other civilizations. (Yes, the world inside the computer is infinitely more important than real civilizations, but I don't think that matters.) Also, if these super-Turing machines are possible, and the real universe is finite, then we are living in a simulation with probability 1, because you could use them to simulate infinitely many observer-seconds.
0Raiden
This is probably true. I think a lot of people feel uncomfortable with the possibility of us living in a simulation, because we'd be in a "less real" universe or we'd be under the complete control of the simulators, or various other complaints. But if such super-Turing machines are possible, then the simulated nature of the universe wouldn't really matter. Unless the simulators intervened to prevent it, we could "escape" by running an infinite simulation of ourselves. It would almost be like entering an ontologically separate reality.

If one were to build a cannon (say a large, thick pipe buried deep underground) and use a nuclear bomb as propellant, could they achieve anything interesting? For example, boost a first stage payload to orbit, or perhaps Earth escape velocity? The only prior art I know of for this is the Pascal-B nuclear test shot.

8gwern
Nuclear space guns have been proposed. Aside from the manhole cover: http://nextbigfuture.com/2010/03/150-kiloton-nuclear-verne-gun.html http://nextbigfuture.com/2010/12/sea-based-launch-option-for-nuclear.html (This appears in Hannu's Quantum Thief trilogy, incidentally.)
4Nornagest
I don't think a working model of this would look much like a cannon. Nukes don't directly produce (much of) a shockwave; most of the shock comes from everything in the vicinity of the warhead absorbing a massive dose of prompt gamma and/or loose neutrons and suddenly deciding that all its atoms really need to be over there. So if you had a payload backed right against a nuke, even if it managed to survive the explosion, it wouldn't convert much of its power into velocity; Orion gets its power by vaporizing the outer layers of the pusher plate or a layer of reaction mass sprayed on it. But it might be possible, nonetheless. The thing I have in mind might look something like a large chamber full of water with a nuke in the center of it, connected by some plumbing to the launch tube with the payload. Initiate the nuke, the water flashes into steam, the expanding steam drives the payload. Tricky part would be controlling the acceleration for a (relatively) smooth launch with minimal wasted energy. (And, of course, you're left with a giant plume of radioactive steam that you still need to deal with.)
3blake8086
I think you would actually want to use hydrogen. It would essentially be a really powerful light gas gun.

As I understood it, the reaction mass for Orion comes from the chemical explosives used to implode the bomb. (The bomb design would be quite unusual, with several tons of explosives acting on a very small amount of plutonium).
0Izeinwinter
There are better options if you want to go nuclear for propulsion. http://www.nasa.gov/pdf/718391main_Werka_2011_PhI_FFRE.pdf It's not an unreasonable amount of mass to get into LEO, and so very elegant as a drive.
4James_Miller
See Project Orion. It's motto was "Mars by 1965, Saturn by 1970."
1blake8086
That's not really related though. I'm asking "what if you build a gun with nukes as propellant?", not "what if you build a plane that rocket jumps through air/space?". The idea is to impart the highest fraction of a single bomb's energy onto a payload. Orion is pretty wasteful in terms of energy conversion.
1CBHacking
Orion requires quite a few detonations, though; even with a massive craft (much of which is pusher plate and shock absorbers) to absorb the impact, you have to use fairly low-yield bombs and each only provides a relatively short period of thrust. You could possibly design something that takes higher yields (especially higher relative to the vehicle mass) that would survive reaching orbit on one detonation, but it would be subjected to extreme acceleration - the kind that would crush any satellite launched thus far - and I suspect there might be too much risk of tumbling given the non-uniformity of the atmosphere.

Both your barrel and your payload need to be able to survive being at the epicenter of a nuclear explosion. Spitting jets of molten metal into space isn't particularly useful.

A variation - an acceleration chamber like a synchrotron (or other circular acceleration system), with a flick to release a payload towards space. not sure if it would be viable on something heavier than a particle, and what would happen. to the payload being stretched in various G-forces, or how high you would get.

I think all you need to do to release the payload is to stop flicking it, so that part should be easy.

Across the multiverse, some universes support life. Some life-friendly universes contain advanced civs which create simulations. The physics of our universe supports an enormous number of sims per basement universe. Thus most of the copies of ourselves probably exist in/as sims.

What if doing housework is actually bad for people? It's certainly something that people have to be trained into, and that a lot of people resist doing. No one does it for the fun of it.

1Gunnar_Zarncke
I'm not sure what you mean by it being 'bad'. Leading to unhappiness? As opposed to even more unhappiness due to a messy house? I disagree with this in it's generality. The ability to to household tasks needs to be trained. Establishment of the habit is another thing. An approach that leads to a relaxed approach to 'chores' depends on the motivational structure of the child (if you imply parenting). An intrinsically motivated (on this kind of tasks) child will likely want to do the tasks if it clear that this is necessary to achieve it's own goals. So if household tasks are routinely coupled to some things the child want/needs for itself like clothing of its choice, access to materials, support in its projects..., then it will do these tasks (as long as it doesn't perceive the dependency as arbitrary, constructed, forced or unfair. Prototype example is my oldest son who has lots of projects for which he needs space and materials. An extrinsically motivated child (more like my second oldest) can be influenced via frequent positive feedback for performing these tasks. Sure. I can confirm that my sons resist doing it in many circumstances. But the details differ widely. Gamification is possible. Though not always. And it has a cost in terms of efficiency. But you don't need fun to want to do it and feel satisfaction from completing it.

Doing housework isn't the same thing as living in a clean orderly house-- someone else might be doing the housework. I'm not sure in what way doing housework might be bad for people, I'm just inclined to think that people's instincts aren't totally unreliable, and people tend to not like doing housework.
1Gunnar_Zarncke
I'm not clear what you are driving at. Actually I wasn't with your first comment either. I agree. I think I see both aspects. I have household help and she isn't doing everything - only big chunks like laundry. Big chunks that can't only be done on the fly. I don't mind doing dishes while talking in the kitchen. Actually with children many household tasks come kind of for free - there isn't much else that can be done while caring for, teaching and in general looking after four boys. Many tasks also carry a lesson and sometimes even serve to avoid boredom on my side. Or are relaxing, But yes, not the tiring ones.
2[anonymous]
I think you two are a bit talking past each other. It is an entirely different question whether doing it is good for a child (I'd say yes, easy productive success and pride) or for an adult, especially a busy one i.e. whether a surgeon is better off doing the ironing after a hospital shift or should rather outsource it to hired help (I'd say the later). Adult instincts are fairly reliable IMHO children's instincts not so much. Also, adults like it if they did nothing but work on the computer all day - it is satisfying to do something "real".
0Gunnar_Zarncke
Oh, they are very reliable ... toward doing only those things that are really necessary. The genes don't know whether the laundry is necessary. It might be it might be not. There will have been comparable tasks in the ancestral environment. It is adaptive to have a drive that looks for more potential.
0[anonymous]
I'd say, it is a good for people to live in an orderly and clean environment, but it is not necessarily good for them to do it themselves - this is why everybody wealthy outsources most of it to hired help. But it could be good for some people e.g. children, the depressed etc. for achieving easy success and learning a bit of discipline. But as long as people can do more productive things almost nobody demands that they should do it themselves - have ever seen a surgeon, regardless of gender, being criticized for not ironing shirts but leaving that to a hired help? (Also fsck everything about ironing - there is a startup in France trying to automate it with some kind of an inflatable human shaped balloon releasing steam, hope they succeed although I would not want a human upper body sized bulky item in our current flat. But I really like my shirts crisp and buying no-iron shirts is a poor substitute.)

A friend of mine does. Not "fun" per se, but she derives enjoyment and satisfaction from it.

A single world language should be designed and promoted. Previous attempts have been too Eurocentric to take advantage of all useful grammatical features that are available.

Alternative option: English is already a de facto world language, and it is well suited to borrowing foreign terms when it needs to, but humanity should be ashamed that it conducts its main scientific, commercial and diplomatic operations in a language with such a defective writing system. Spelling reform (or a completely new, purely phonetic alphabet) is urgent. I would advocate adapting Hangul for that purpose.

9MotivationalAppeal
The International Phonetic Alphabet was originally meant to be used as a natural language writing system (for example, the journal of the International Phonetic Association was originally written in IPA: http://phonetic-blog.blogspot.com/2012/06/100-years-ago.html). Between IPA's theoretical (physiological) grounding, its wide use by linguists, and its near-legibility by untrained English literati, IPA is over-determined as the obvious choice for a reformed orthography, if English were every made to conform phonetically to a standard pronunciation. That said, it's not going to happen, because spelling reform is not urgent to anyone with capital to try it. Like, someone could make a browser extension that would replace words their IPA spellings, so that an online community could familiarize themselves with the new spelling, but no one has made that, or paid for it to be made, and this places a strong upper bound on how much anyone cares about spelling reform.

I'd never thought of such an extension, and my first thought when you mentioned it was "I'd fund that kickstarter". Could we organize such? How much work would it be likely to take/how much would it be likely to cost?
5Viliam
Is there a chance to agree on which gramatical features are useful? For example, what colors does the language have words for? Does it distinguish gramatical singular and plural? How about dual? How many tenses? Clusivity? Honorifics? Etc. My intuition is that in a "perfect" language all these things should exist, and all should be optional. (Not sure about the colors; perhaps we should have separate words for "green" and "blue", but also one for "green or blue", and also one for "light blue" and one for "dark blue" to make everyone happy. I hope the list would not grow too much.)
5garabik
There are so many constructed languages already that you do not need to design anything, if you have some criteria, just pick one that suits you, brush it up and maybe replace the vocabulary. And then goes the minor issue of promoting it and gaining speakers :-) English is rather badly suited for an international auxiliary language, as the things go. But still better than French or Chinese, all things considered. Spelling is OK, it's the pronunciation that sucks :-) And its weird syntax and internally inconsistent vocabulary. You really, really do not want phonetic writing system - phonemic is what you should go after, but morphophonemic has certain advantages too, especially for non-native speakers. If you match your phonology to 15th century Korean, sure. Not so much otherwise without a substantial reform and introduction of new letters. Anyway, Hangul is more suited for a morphematic writing system, not phone[mt]ic one.
5D_Malik
Playing devil's advocate: Archaic spelling rules allow you to quickly gauge other people's intelligence, which is useful. It causes society to respect stupid people less, by providing objective evidence of their stupidity. But I don't actually think the benefits outweigh the costs there, and the signal is confounded by things like being a native English-speaker.
6fubarobfusco
Spelling is more a gauge of how attentive you were in early schooling than of how intelligent you are. It's basically a form of conspicuous consumption of the scarce resources of childhood attention and teaching time. The cultural notion that bad spelling is an indicator of stupidity is self-reinforcing, though: it prevents English from undergoing spelling reforms like those German, Spanish, Russian, and many other languages have had, because any "reformed" spelling will necessarily look like ignorant spelling. Because English spelling is unusually difficult, it is a challenge. Because it is a challenge, people who have mastered it care about the fact that they have mastered it. And because of that, it can't be made easier.
9Lumifer
I think it's a gauge of how much you read. Bad spelling is not an indicator of stupidity, but an indicator of not having read enough.
8Viliam
It is much easier to do a spelling reform in a mostly illiterate country, where you can defend it by saying "look, most people can't read, we need to make it easier for them". Having a monarchy or dictatorship also helps to introduce the changes quickly and everywhere. https://en.wikipedia.org/wiki/Reforms_of_Russian_orthography Today I learned: Russian once had a letter for "th", but it was removed and replaced by either "f" or "t".
0garabik
Indeed. Look at the rejected recent German orthography reform – and the changes were (relatively) minor. Or the messed up Slovak orthography reform from the '90s – and that was mostly a few acutes here and there.
2gjm
I'd assume it's a measure of both attentiveness and intelligence. And also of how much reading you did when young. I expect all these things correlate enough to make it hard to disentangle them, but just on first principles it seems obvious that you'll learn spellings better (1) if you generally learn things better, (2) if you're exposed to more correct spellings, and (3) if you're paying more attention to spelling relative to other things. I agree about the difficulties of spelling reform. Perhaps sufficient support from high-status intellectual literary people might get past the "reform looks like ignorance" problem. Strong support from George Bernard Shaw wasn't enough for English in the early 20th century; perhaps it could be done with a large enough coalition of obviously expert people, or incrementally with each smaller step perhaps being easier to accept. (Whether it would be a good idea, I don't know. I've not seen evidence that the difficulty of spelling in English -- which I think is one of the hardest-to-spell major languages -- causes much actual harm. And yes, for the avoidance of doubt, the Mark Twain thing [EDITED to add: very probably not actually written by Mark Twain] I linked to was written as a joke and not a serious proposal; I linked to it because I think it's funny.)

Spelling reform will fail because of regional differences in pronunciation. Also, spelling reform is bad for culture since it means that people taught the new system will be unable to read older material.
6Good_Burning_Plastic
Well, you won't be able to accommodate everybody's pronunciation, but with a decent diaphonemic system could allow you to deduce the pronunciation of almost all words in most mainstream varieties of English from their spelling.
4John_Maxwell

4polymathwannabe
Indeed, it's problematic that English is open source instead of having a central authority. But just like the printing press standardized written German, the internet may make spoken English more homogeneous. In the spirit of efficiency, my not-at-all-humble opinion is that local linguistic variations ought to be regarded as a bug, not a feature. Regionalism be damned. ...so you can't read Beowulf because you don't know the Saxon script? The People's Republic of China is the biggest example of a successful comprehensive script reform. Korea loves its totally artificial Hangul, and Turkey is doing fine with the Latin alphabet. Japan took a lot longer to standardize its script, but it makes a lot more sense now than in the past. In each country, scholars who want to work with old books can still learn the former scripts.
3Jiro
The language of Beowulf is far enough from ours that I need to do a lot of studying before I can read it anyway, so the additional effort to learn a script wouldn't make much of a difference. If, for instance, Shakespeare was in a different script, it would certainly cut down on the number of people who read Shakespeare (unless translated versions became widely available, which is possible for Shakespeare, but would not be true for most old works.) Furthermore, doing such reform now would mean doing it after cheap mass market printing, which would make the effect much worse (and unlike Shakespeare, the works would be copyrighted, so if the owner refuses to publish a translated version, nobody else could). I don't know how many mass market books there were in Turkey in the 1920's.
2Douglas_Knight
Simultaneous with the script reform in Turkey was a language reform that tried to remove Arabic words, to align it with the West. Not being able to read the old books may have been the goal.

Um, spelling reform large destroys the benefits of already being a de facto world language.

You cite the language's tendency to borrow foreign terms as a positive thing. Wouldn't that require an inconsistent orthography?

In its current state, English does tend to borrow terms without changing their spelling (e.g. plateau), but in my proposed system they would all have to be adapted. Many languages already do that: Spanish borrowed football and turned it into fútbol.

How would they identify what's a mutation and what isn't? (Extreme rarity in the rest of the population?)

Poorer people are happier. Alternatively, even when the aggregate or average level of happiness is not higher, some factors in it are higher, while other hugely negative factors (i.e. actually being poor) reduce the average or aggregate greatly.

The positive factors are strong social bonds. The problem is that middle-class people are trying to form friendships through just hanging out with people or trying to find common, shared interests. This is not strong bonds.

Poor people need to help each other, it is a basic necessity, and they form strong bonds this... (read more)

Evidence please. Your idea relies heavily on the thesis that poorer people are happier and have better social relations than rich people, do you have anything not anecdotal to support that?

My experience of seeing poverty in the US is that it comes with or from a whole host of other social problems like addiction, untreated physical and mental health issues, abuse, anxiety, overcrowding, fear of violence. These co-morbid problems are not conducive to neither happiness nor strong social ties, except in an unhealthy codependent way. I do know that children who grow up in poverty (without malnutrition) have brain development issues because of all the toxic anxiety and stress they were exposed to as a child, and that these problems persist through adulthood if untreated, even if the poverty conditions are removed. http://www.newyorker.com/tech/elements/what-poverty-does-to-the-young-brain

In fact, from a precursory google search, every article I see about the neurological effects of poverty is that it increases daily experience of negative emotions, chronic pain, increases the odds of all kinds of unpleasant experiences and mental health issues, and comes with a constant sense of anxiety.

The essence of poverty is that you cannot just buy all the things you need, you sometimes need to make them yourself or borrow.

Nope. The essence of poverty is that the choices available to you are severely limited because of lack of money.

9Jiro
1) I don't believe in maximizing happiness. That leads to wireheading, and also to the blissful ignorance problem where being falsely convinced of X is considered as good as actually having X. 2) When people who are poor have to make or borrow to get things, making and borrowing has a cost. The fact that richer people won't pay this cost shows that the cost is larger than the monetary price. If anything, this is an example of a poverty trap, since it means poorer people have to pay higher costs for things than richer people.

4Viliam
While I disagree with your description of happy poor people, I admit that the idea of creating stronger social bonds is appealing. Well, of course they would have to be social bonds with people I like, who would not abuse me... but then, doesn't the mere possibility of choosing people to bond with already reduce the strength of those bonds? Okay, we don't have to go to the very extreme, and still can try to increase the strength of the bonds, without necessarily maximizing it. There are things people need help with, even if they are not necessary for survival. If you want to make a big project, you need people to cooperate with. So, have a dream, make it public, find people to cooperate with... and if you all feel strongly about the project, you will have the bonds. Just start an NGO. If you want to compare with the mega-rich, find a group of people willing to found a cooperative, in a spirit of "together we all get rich; no one gets left behind". As opposed to usual startups where people try to do things alone or in very small teams; and hire other people as replaceable pawns. (Note: in the cooperative, you can still hire the pawns later; many cooperatives do; you will only have the strong bonds among the local aristocracy, but the aristocracy can have dozens of members.) Now you are competing against the rich companies, and the economical situation of each of you depends on your mutual cooperation.
3NancyLebovitz
I haven't been poor myself, but I'll offer some weak evidence in favor of a weakened version of your thesis. I've seen a fair number of people say that when they were children, they were poor but didn't know it, and they were happy. This suggests that (presumably above some level of destitution), low relative status affects people more than absolute wealth. I can't remember whether being poor but happy as a child is correlated with living in the country, but this wouldn't surprise me. It may also be true that children are better at being happy than adults, and this could be worth some study.
2buybuydandavis
Some people trade off the pursuit of money for living in areas with stronger and more generally dispersed social capital, with cultures of mutual self help, and spend more time on building their own social capital within it. They're poorer financially, but wealthier socially. But some people are poorer financially in areas where the social capital is generally poor as well, and particularly poor for the financially poor. I think the problem is that wealthier people can buy the services they need, and so do so. Buying it doesn't impose a burden on your social equals, and so doesn't require taking on such burdens in a reciprocal fashion. As you go up the wealth scale, for more and more things, you'd rather trade off money for time and effort, and you're able to buy that trade off from people who would rather have your money than their time. This is apparent to all, people who make less than you, and people who make the same. The people who make less will likely resent your requests for help, certainly if you haven't yet banked some help to them first, but even if you have, they're still likely to resent your trading off their time versus your money, knowing that you don't see it as worthwhile when it's your time vs. your money. The people who make the same as you probably have the same time vs. money preferences as you do, would rather trade off their own money for their own time on their own problem, and so certainly won't want to be spending their time on your problem, when you obviously should just be spending your own money instead. I think you're right that you get social bonding out of relations of reciprocating mutual aid, and also right that this gets harder to accomplish as you become more wealthy. But I think you're wrong about the poor being necessarily happier, as you assumed that the reciprocating mutual aid would naturally occur if your'e poor. A lot of social and cultural capital that doesn't exist everywhere is required to make that happen.

Well, poverty is not correctly measured by money alone. If the land outside the city is cheaper, and you can grow your own vegetables in the garden, you need less cash to live at the same level of comfort. You usually have less options outside the city, especially less of those options that you or me would consider important, but many people are okay with such life. A poor rural person could be one who doesn't own a house and a garden. Probably not too happy.

Sure, they could simulate that, but I'm not sure whether simulated neighborhood cooperation sticks out with regards to effectiveness at all compared to things like hanging out, sharing interests, engaging in cooperative sports and games. I suspect that the main factor that isolates rich people is rather the prevailing inequality which separates them from 95% of the population. The envy they receive and the cognitive dissonance they get from being aware of the inequality but letting the responsibility diffuse, makes them anxious. I guess reducing inequality is a much more effective and sustainable solution to this problem.

Cheap and ubiquitous GPS allows us to eliminate the guesswork from catching repeat offenders. Anyone convicted of robbery or assault is tagged with an ankle monitor. Any time a crime is committed, it's checked against the GPS records of criminals.

Ankle monitors are surprisingly annoying to wear. It would be a big, long-term punishment that would probably come on top of a prison sentence.
0Illano
I'm surprised no one has pushed through a cell-phone tracking app as a replacement for the ankle monitors. Sure, its not as secure, and may be left somewhere/forgotten/etc. but if you included it as a condition for parole/probation, you could probably get pretty high usage rates, with little added cost and annoyance.

Sure, the first point is why I think it will work. As for the second, sure, it may not be 100% accurate, but it would be better than nothing, and even negative information could be useful. (e.g. Person X did not have their phone on during the robbery, but otherwise normally has it on them 100% of the time.) I agree it's not an ideal solution, just something that might help a little.

Justice departments notably have trouble keeping up with modern technology. Where I live, it's still impossible to get a digital copy of your file (leading to a case where someone ate an important document and was able to go free on a technicality). Not just that, but smartphones are not quite ubiquitous yet. Either you require the person to purchase one, or have the state purchase one, neither of which is ideal. I suspect there are also legal and human right problems, since ankle monitors are already used as a form of punishment, but have never been used (as far as I know) as a parole/probation measure.

Society should implement the following procedure to fight off MRSA: 1) Find a strain of bacteria that occupies the same environmental niche as MRSA, but is not resistant to antibiotics. 2) Mass produce this strain in factories, and then spread it by airborne distribution vehicles (maybe drones). This will tilt the evolutionary balance away from the resistant strain and towards the non-resistant strain.

8tut
Soil bacteria, including Staphylococcus aureus, are already everywhere. I don't see how spreading more of them would reduce the old ones.
0Daniel_Burfoot
The theory is that most environmental niches will already be maxed out in terms of how much MRSA-like bacteria they can support - if they weren't, the bacteria would just reproduce more. So say your backyard can support 1e9 bacteria. Of that, 5e8 is antibiotic-resistant bacteria, while 5e8 is regular bacteria. Then you add another 1e9 regular bacteria. Now the backyard is overcapacity, so the 2e9 bacteria will compete for survival until only 1e9 are left. Assuming that the antibiotic-resistant bacteria has no other advantage over regular bacteria, then after the winnowing there will be 2.5e8 antibiotic-resistant and 7.5e8 regular bacteria - a reduction from 50% to 25%. Every subsequent application of the procedure will exponentially decrease the proportion of resistant bacteria.
2[anonymous]
More to the point though, any time antibiotics are used the bacterium with antibiotic resistance takes over. There is a reason that it is often spread in hospitals, where sick people on antibiotics are, and in pig farms where ridiculous loads of antibiotics are used to increase growth rates. What is necessary is breaking the chain of spread from antibiotic-treated niche to antibiotic-treated niche, and making sure there aren't places like said pig farms where the selective pressure is constantly applied.
0tut
This would also increase the number of Staphylococcus relative to other bacteria in the ground. And these bacteria can transfer DNA to each other, including resistance genes. So many of your added bacteria would turn into MRSA, and if there is enough antibiotics in the environment to maintain the MRSA prevalence without your intervention, then you just might end up increasing the amount of MRSA in the region.
6drethelin
This would at best be a temporary solution, since this was pretty much the status quo before MRSA was as big a deal as it is now. The continued presence of antibiotics will exert a selection pressure in favor of MRSA.
0Daniel_Burfoot
So.... we keep the factories running. Seems like a small price to pay for the continued effectiveness of antibiotics.
1drethelin
If your plan is to spray MRSA into the air forever I'm pretty sure that will lead to far more deaths from untreated or treated too late infections than you would be saving by making some subset of existing infections treatable.
0Daniel_Burfoot
Maybe air-spraying is the wrong distribution method - possibly it would be better to just use trucks or whatever. There is an adjustable parameter which is how many bacteria we add to the environment per unit time. That parameter controls how quickly the resistant bacteria are replaced by non-resistant bacteria. But regardless of the value, the shape of the function of resistant bacteria population vs time should be exponential decline. So if you are worried about extra infections, you can select a small value for the replacement parameter. Say you follow a schedule where on the first of every month, you release a bunch of bacteria, increasing the total population in an area by 1%. Then over the course of the month, the population falls back down to its initial value. If you do this for many months, you will eventually cause a large impact to the population of resistant bacteria, while never increasing the aggregate number of bacteria in the environment by more than 1%.

If you throw out justified you then consider what we intuitively consider delusional beliefs who happen to be accidentally true to be knowledge. Which conflicts with intuition. You can always bite the bullet on any conflict but that's boring.
0eternal_neophyte
It depends on what you call "delusional". Just to be clear: I'm not arguing that justification is impossible, but that "at bottom" all our beliefs rest on uncertain axioms that are provisionally treated as certain, but which aren't justified. Aesthetic considerations such as boring vs. interesting, elegant vs. obtuse, natural vs. tortured then loom much larger in the actual part they play in determining beliefs than supposed certainty about axioms. Additionally there's a problem with whether it's actually possible to truly believe something without justification. If your beliefs don't make contact with your experiences then what exactly is it you're believing in?
0MathiasZaman
Are there examples of interventions like this working out well?
0Thomas
Sure. Camels in Australia. Dingo in Australia. Especially hippos in South America, where they were introduced by the late drug cartel lord Pablo Escobar. See Hippos are ideal for South America. They were almost missing there. So I guess is the case about polar bears and Antarctica.
9polymathwannabe
What? Australia is the poster child for why you shouldn't randomly introduce species where they don't belong. Polar bears would be disastrous in Antarctica. Their hibernation would need to adjust to the reversed seasonal pattern. Penguins aren't adapted for sharing their habitat with a large land predator. And as for those hippos, the same article you link says it's actually hell to deal with them. Also, the history of how they got brought here is tainted with too much pain.

Sidetrack: "Randomly" is ill-defined. Is introducing 40 bird species that were mentioned in Shakespeare to North America random?
0polymathwannabe
Following Shakespeare's list when it already existed was probably not random, but Shakespeare's choice of what birds to mention in each of his plays was likely determined by the constraints of meter, rhyme, and metaphoric value, which in a natural language are random parameters. Edited to add: randomness may have also played a part in the choice of writer (i.e. Shakespeare instead of Goethe or Homer or someone else).
0NancyLebovitz
One definition of random is compressible-- it's shorter to say forty birds mentioned in Shakespeare than to list the birds. I'm pretty sure the choice of writer wasn't random-- Shakespeare is tremendously respected by a lot of English speakers, but the idea of exporting British birds to North America to make it seem more homey seems very random.
1IlyaShpitser
A sequence of 40 zeros is highly compressible, but does not look random. You mean a sequence "looks random" if it's not very compressible -- right? That is, the sequence is a member of the appropriate typical set: https://en.wikipedia.org/wiki/Typical_set Or maybe you meant "looks random" means "compressed already." (???) A zipped file expressed as a bit sequence looks random.
0NancyLebovitz
I'm sorry, I meant to say that randomness is not compressible.
3Thomas
It's a crazy idea thread, not necessary a good idea thread. How else than randomly, any species has been introduced? Ever?

Okay, by crazy but not necessarily good idea: eating a bag of pine cones.

You're committing the naturalistic fallacy. There's a difference between dumb nature acting blindly and rational people making choices they know they'll be held accountable for. However, I know I may be accused of naturalistic fallacy because I'm arguing in favor of leaving current ecosystems the way they are. While is it true that not all introduced species have been harmful, this is very difficult to predict, the specific examples being discussed are more likely to end up terribly, and historical experience with introduced species has leaned toward it being a bad idea. Humans are the ultimate invasive species, and we've been great at killing everything in our path.
0Thomas
About 20000 species invaded British isles after the last ice age. Mostly with no human intervention, some with human help. It is one of the most beautiful places on Earth. Isn't it? But this is only a thread about crazy ideas. That's all. Thought provoking, not necessary politically and/or environmentally correct thinking, for Christ sake!
3polymathwannabe
The record on species introduced to the British Isles is rather mixed. Of course it looks peaceful; dead squirrels tell no tales.

Of course, it's biology. Something we should transcend. But that's another topic.

I just thought about how valuable genuine personal feedback is and in the context of LW that there is some tradition to post anonymous feedback forms (see .g. here). And I wondered: Could this be made into something more structured and valuable? Assuming feedback is valuable could a medium be found that supports that? I wondered whether a forum like Stackoverflow could be medified and employed to give and receive feedback. Or an addition to an existing foum for anonymous feedback. The difficulty is if anonymity is provided it can be abused. Esp. if you en... (read more)

Formspring was a simpler version of this, and it devolved into bullying. That's a failure mode of any anonymous feedback system.
0Gunnar_Zarncke
Yes, I guessed so. Therefore the reviewing.
2Nornagest
There have been a few apps based around this, though usually lacking the karma part. The one that comes to mind is Honesty Box for Facebook. (Which may no longer exist? I last heard of it several years ago.)
2g_pepper
Here's a web site that supports anonymous feedback, although I don't think it does anything like the karma calculation or review process that you mentioned. I have not used it; I just happened to notice that another LWer was using it when I was reading his comments earlier this week.
2John_Maxwell
I have an anonymous feedback link in my LW profile that's been present for over a year. I've only gotten a couple pieces of feedback.

Discussion of this thread goes here; all other top-level comments should be ideas or similar.

8Jiro
I think "crazy idea" is underspecified. The kind of crazy idea that you probably want is an unusual way of meeting an acceptable goal and based on acceptable premises. You don't want someone posting "kill all the Jews" and you don't want someone posting "in order to get rid of the lizard invaders, we should..." even though those are certainly crazy ideas. Of course, nobody would post those things outright, but there are shades of gray where the goal or premises are somewhat questionable, even if not outright as bad as killing all the Jews. (I think, for instance, that the "freedom from fear" post below is close to this.)
4Gunnar_Zarncke
Could you suggest a more precise definition? Then I or somebody else can use it on a follow-up post.
1James_Miller
A crazy idea is something most people would quickly dismiss because of the absurdity heuristic. We want crazy ideas that on reflection appear to have merit.
0Gunnar_Zarncke
Sure. But how to know beforehand? The absurdity heuristic works also on yourself. But then "crazy idea" wasn't meant literally for more inspirational.
0James_Miller
Good point, although you can develop a feel for what others consider absurd.
7spriteless
Nitpick: your post is tagged cary idea, not crazy idea.
2Gunnar_Zarncke
Thank you. Fixed.
4SilentCal
By my rough casual count, around half of the ideas here that are action proposals have been either attempted or proposed by serious bodies. I don't think this is a bad thing at all.

Does that mean people aren't being nearly crazy enough?

Is this a revival of the Munchkin Ideas thread?

I like the idea of this thread. I often have crazy ideas but few spring to mind right now. I also wonder if the thread is off-topic for lesswrong. For being distracting and not rationalist or progress towards a goal.
0Gunnar_Zarncke
In this generality it is off-topic, yes. But by making it into a separate thread this provides a niche for it. I also wondered whether I should restrict ideas to those tangential to LW topics but decided against it. Maybe for a later installment.
1Elo
In this way I believe this is a shift to destroy the old garden-form that we have had. Stupid silly and fun, but no longer the focussed LessWrong that it used to be.
0Gunnar_Zarncke
Now that I see the amount of response I think I really could have made it more focussed. Now.
0Gunnar_Zarncke
I'm amazed by the amount of response this has caused. Must by far be the most commented on post of mine. And all of that in response to a five minute crazy idea. I wonder whether I should post more of these 'crazy' ideas.
  1. If you could take a treatment which granted you immortality and eliminated your aversion to death, would you? More interestingly, what would you think afterward of those who desired to do the same? What if two classes of people resulted. What would they think of each other? How long would you end up living?

  2. Can we post the sequences on a thousand blogs marketed a thousand different ways (some for housewives, or for business people, or for students, or for political science, or common people of common sense, hobbyists, etcetera) to produce a more rapid di

2gjm
#1 sounds like it might be an interesting question, but I'm not sure I understand it. A large part of my "aversion to death" is simply the fact that I have things I want to do in the future. Is this hypothetical treatment meant to get rid of that? (Surely not, right?) If not, what exactly is being eliminated? Just some visceral reaction of horror at the thought of death? What about aversion to other people's deaths? (My immediate reaction: Yes, of course I would take it; whyever wouldn't I?) #2 sounds rather culty, but in any case I doubt it would work. If you want a "rationality for housewives[1]" series, I think you need to write one; the LW "Sequences" are written for a particular kind of audience and I don't think its intersection with housewives is very large. [1] I'm not sure "housewives" is the best term, unless you really want to exclude any men who happen to be filling that role. Homemakers? With #3, don't you think the evolutionary process would be impractically slow?
0Viliam
If you'd rewrite it for each audience, that would be great! Otherwise it would feel like spam.

I have a cluster of related physics ideas that I'm currently trying to work out the equations for. For the record, I am not a physicist. My bachelors is in computing specializing in cognitive science, and my masters is in computer science, with my thesis work on neural networks and object recognition.

So with that, my crazy ideas are:

No, neutrinos have all sorts of different properties than protons (spin-1/2, three generations, take part in weak interactions) regardless of their energy-momentum.
-1Darklight
Regardless of their spatial energy-momentum. But if I'm not mistaken, all these properties are associated with particles that have mass? So, I mean equivalent in the sense that they could be packets of temporal kinetic energy (in the form of their mass), in the way that photons are packets of spatial kinetic energy. It's quite possible that because their kinetic energy is temporal rather than spatial, they should have different and complementary properties compared to photons. Or maybe the hypothetical Axions are a better candidate. Edit: Or for that matter, the Higgs Boson.

If I want to learn all the material on MIRI's research guide as quickly as possible, do I have to get a day job and fuel my own education, or is there a cult that would take me into their deep, dark dungeons as a slave, so long as all I did was study?

I guess if there were just some other way I could more easily facilitate my studies that would be fine too, it doesn't have to involve servitude to shady folk.

You could save up money for a few months then move to a country with a very cheap cost of living and live off your savings.

A college education is a terrible investment for the average person in today's economy. The money and (more importantly) the time spent would be much better utilized to obtain the same human capital and signaling power at a cheaper monetary cost and a faster rate than those at which universities are willing to provide.

7Gunnar_Zarncke
How?
4Illano
Depends a ton on where you go and what you major in. PayScale has a ranking of a ton of colleges based on their 20-year average incomes compared to 24 years of average income for people with a high-school degree. There probably are some special cases at the tails that would benefit more from not going to college, but for the average college-goer, it is still probably a halfway decent investment.

Doesn't it tell you whether it was worth going to college 20 years ago?

When I prime myself with the Wikipedia article for executive function, I feel significantly more capable and confident in my cognitive functioning. I don't even have a crazy idea why. Funnily enough, IIRC when I did an online test for planning, the Tower of Hanoi...well, I didn't get anywhere with it. I couldn't even complete it. So I'm maybe messed up in some way.

Does Dust Theory imply that every time you go to sleep, or lose grasp of your surroundings, your dominant reality collapses and a new one takes shape? After all, it's only your experiences that create your coherent world. I think it would be similar to the Autoverse's 'removal' of Permutation City from its reality.

EDIT: Hmm, no, there would just be a slow degradation of consciousness. Nothing that would explain my memories of dreaming last night and taking a ninety-degree turn back into reality upon waking up; that dream would have become my reality. So I'm fairly confident Dust Theory is false, because of the sheer unnecessary baggage my reality appears to have.

Dogs are incredibly good at perceiving through their nose. They smell almost everything around them including other species' old feces. Some dogs even eat their own. A lot of smells must be something unbearable with human nose but they take them well. If their physical mechanism enables them to embrace all kinds of disgusting smells with less rejection, I think the same mechanism also makes the nature of dogs more tolerant and altruistic than that of human being who are easily disgusted. Dogs are overall just nice : )

2RedErin
Dogs were domesticated in such a way so that their very existence depends on them being nice to humans.

If the many-worlds interpretation is truly how the world is, and if having multiple copies of myself as an upload is more valuable than just having one copy on more powerful (or distributed) hardware, then...

I could bid for a job asking for a price which could be adequate if I were working by myself. I could create N copies of myself to help complete the job. Then, assuming there's no easy way to meld my copies back into one, I could create a simple quantum lottery that deletes all but one copy.

Each copy is guaranteed to live on in its own Everett branch, able to enjoy the full reward from completing the job.

Well, I'll admit I only read the title before diving into the comments, and in that context it's sufficiently obvious. Although I'm twisted enough that adding descriptions like "ideas that spontaneously come to mind (and feel great)" just makes it funnier.

I'm ambivalent about whether a particular fact makes this a better or worse joke. That fact is that a lot of of people think that "lizard people" is a dog whistle for Jews. A Canadian court decided that it isn't.

Was anyone preserved for years and later revived in that movie? If anything, Anna's predicament (being slowly turned into ice) is a terrible threat to avoid.

I like to imagine that eventually we will be able to boil the counter-intuitive parts of quantum physics away into something more elegant. I keep coming back to the idea that every current interaction could theoretically be modeled as the interactions of variously polarized electromagnetic waves. Such as mass being caused by rotational acceleration of light, and charge being emergent from the cross-interactions of polarized photons. I doubt the idea really carves reality at the joints, but I think it's probably closer to accurate than the standard model, which is functional but patchworked, much like the predictive models used by astrologers prior to the acceptance of heliocentrism.

What if you put little electricity-generating windmills on top of an electric car. Could they produce enough electricity to help propel the car, or would the energy produced be counteracted by the drag added?

4Dagon
Pretty clearly the longitudinal wind would be more than canceled out by drag. You might be able to get some net power from any cross-wind that is present. But for that, you're better off with fixed windmills used to charge your battery.
