I'm confused here: You seem to be analyzing a troubleshooting process. How exactly did the troubleshooting process fail? I can see that there's some criticisms of what was done. But I don't see how this troubleshooting process resulted in disaster.
These are some very good links. I'm still digesting them. Thank you!
I've at least gave them all a once over (with the exception of Permutation City which awesome as it looks suffers from my general failure to incorporate fiction into my life) but definitely need to dig deeper. There's so much cool stuff out there that I'm still scratching the surface on.
Hans Moravec's Mind Children, I think comes closest to my argument. but stops short of stating that quantum suicide type scenarios might skew our understanding of physical law.
Anyways I'm just curious as to what else you've seen in a similar vein.
I get the sort of unrestrained woolly thinking that comes from a diet of too much insight porn and an overtrusting one's own ideas. Let me assure you that I don't particularly trust my suspicion here. My aim is to see if it is a good idea or not and if it is a good idea see how far it goes. I figure if someone can provide an extremely compelling argument as to why it's not true then that itself would probably be pretty interesting!
On the subject of quantum mechanics my intent is not to explain a mystery with another mystery fill it with secret sauce and...
This is exactly the suspicion I have. The "real" physical laws could be quite different from the "experienced" physical laws. If this idea is correct physicists are only getting a small piece of the story of how the universe really operates.
It seems to me that this sort of behavior could (with sufficient refinement) provide an account for some of the more bizarre aspects of physical law. An obvious target is the counterintuitive statistics that make quantum mechanics so spooky.
It would also be place where physicsists could stuff thei...
Median expected behavior is simple which makes it easy to calculate.
As an electrical engineer when I design circuits I start off by assuming that all my parts behave exactly as rated. If a resistor says it's 220+10% Ohms then I use 220 for my initial calculations. Assuming median behavior works wonderfully in telling me what my circuit probably will do.
In fact that's good enough info for me to base my design decision on for a lot of purposes (given a quick verification of functionality, of course).
But what about that 10%? What if it might matter? On...
I'll dig a little deeper but let me first ask these questions:
What do you define as a coincidence?
Where can I find an explanation of the N 2^{-(K + C)} weighting?
I'm digging into this a little bit, but I'm not following your reasoning. UDT from what I see doesn't mandate the procedure you outline. (perhaps you can show an article where it does) I also don't see how which decision theory is best should play a strong role here.
But anyways I think the heart of your objection seems to be "Fragile universes will be strongly discounted in the expected utility because of the amount of coincidences required to create them". So I'll free admit to not understanding how this discounting process works, but I will ...
A few brainstormy ideas:
Survival/Sustenance - Food/Water/Shelter/Safety
Humor - Jokes/Comedy
Intimacy - Feeling emotionally connected/Physical Affection/Proximity
Validation - Positive Feedback on emotions/feeling understood/feeling that one is good and one matters
I'm not quite grasping what you're trying to get it here. Please do elaborate and clarify!
When you say "It's irrelevant" and "it doesn't provide any useful information or anything that should guide your behavior" what are you referring to?
Choosing to go for chemo and jumping off a bridge should have different results, The difference between the two results would be the basis for the decision. I don't see how fragile universe hypothesis or MWI should undermine that.
As for the relevance of other timelines, I have four answers:
MWI all
Certainly it would do that, but that could have other effects. For instance, let's say that the presence of a magnetic monopole would rapidly nucleate a vacuum decay event which otherwise would not occur. That effect might explain why the standard model does not include magnetic monopoles.
I'll have to dig into mangled worlds, It seems pretty interesting. Will report back with results, hopefully.
My objection is to the subjective experience of immortality. The multiple worlds gives rise to the illusion of probability. where it seems to us that quantum outputs are chosen randomly (because the vast majority of us experience arbitrary sequences when performing a series of quantum measurements). It is proposed that we should expect ourselves to find ourselves eventually living far beyond our natural years because of this observer selection effect. I would counter that that expectation comes from a naive view of selfhood that treats it like an all-or-nothing thing rather than something far slipperier.
I don't deny that some timelines have versions of me that may "live forever".
So yes, annihilation refers specifically to any process that would at light speed render the universe lethal to life as we know it. I think of it sort of like living on a bubble that's always bursting (in timelines we don't observe). There's something left over but it's pretty unrecognizable.
Any account of the origin of the universe is probably going to have some anthropic consideration, so Boltzmann brains are not a unique problem. But I think fragile universe hypothesis may be an asset in solving it. Conventional cosmology calls for a short lived act...
I'm not sure what you're trying to draw from here, but I don't think MWI requires an infinite number of possibilities.
What matters is in my interpretation of Tegmark's view is that there are many many more cases (by infinite or finite measure) where it works properly than cases where it doesn't.
Example: 499,999,999,999,000 cases cause death without observer experience 500,000,000,000,000 cases do nothing 1000 cases represent equipment failures
We should expect that the subject can predict for himself the do nothing case will occur with extremely high probability.
I've seen a number very small mentions like that, but never anything giving it more than passing consideration. In addition, I haven't seen anyone postulate that this could be distorting our view of other physical laws.
If you've come across something more, I would love to see it!
Quantum mechanics is definitely not immune, that's where we should see the manifestation of the bias I'm proposing. When I refer to Everett many words I'm referring specifically to the property of it where an observer "branches" into multiple successor observers (which I extend to include branches where there are no successor observers).
But which laws would be affected and which would not, I'm not at all certain. It could be some, or all (or, of course, none, if I'm wrong). My proposal is to use this sort of reasoning to develop "deeper" fundamental laws.
Well for better or for worse! Here it is!

The happiness of stupidity is not closed to me. By the time I've made 1 rational decision (by whatever metric one wants to use) I'll have made 100 irrational ones. Stupidity and irrationality is built into the very way I operate.
I am primarily composed stupid and irrational beliefs and I am continually creating more.
You don't choose to be irrational, that's the default position.
Rationality is a limited precious resource that you use to diagnose and fix problems within the irrational milieu of systems and subsystems that make up your mind.

Hey y'all, I come here both as a friend and with an agenda. I'm scary.
See I have a crazy pet theory... (and yes it's a TOE, fancy that!)
...and I'd love to give it a small home on the Internet. Here?
This like to share it with you because this community seems to be be the proper blend of open minded and skeptical. Which is what the damn thing needs.
Anyways I've lurked for quite awhile, and you guys have been great at opening my mind to a lot of things. I figure this might be good enough and crazy enough to give something back.
As a personal note, I'm curre...
So yeah. the gold standard is. of course. scientific prediction. My idea is very far away from such a thing! I actually do have some background in quantum mechanics (I have a physics minor :P) and at one point actually did have some understanding of Hamiltonian Operators and eigenstates and bra-ket notation. However that's a far cry from the sort of needed mathematics to really understand the implications of what I'm talking about (this is why they say a little knowledge is a dangerous thing)! What I do have is enough knowledge to tentatively pose that... (read more)
