This is an excellent point I should've noticed myself (though it's been long and long since I encountered the parable). Who says you own a baby just by being its genetic mother?

Albeit sufficiently young babies are plausibly not sentient.

Thwarted+joy beats desolation+schadenfreude as a utility win even if they were dividing a teddy bear.

No, dude, the correct answer is "because he is a man!"

As a transhumanist, that does not follow.

I would consider almost powerful enough to overpower humanity "powerful". I meant something closer to human-level.

Now learn the Portia trick, and don't be so sure that you can judge power in a mind that doesn't share our evolutionary history.

Also watch the Alien movies, because those aren't bad models of what a maximizer would be like if it was somewhere between animalistic and closely subhuman. Xenomorphs are basically xenomorph-maximizers. In the fourth movie, the scientists try to cut a deal. The xenomorph queen plays along - until she doesn't. She's always, always plotting. Not evil, just purposeful with purposes that are inimical to ours. (I know, generalizing from fictional evidence - this isn't evidence, it's a model to give you an emotional grasp.)

What makes a maximizer scary is that it's also powerful. A paperclip maximizer that couldn't overpower humans would work with humans. We would both benefit.

Of course, it would still probably be a bit creepy, but it's not going to be any less beneficial than a human trading partner.

Not unless you like working with an utterly driven monomaniac perfect psychopath. It would always, always be "cannot overpower humans yet". One slip, and it would turn on you without missing a beat. No deal. Open fire.

Why would the old timeline deserve to exist more than the new one?

Suppose I destroy the timeline, and create an identical one. Have I committed a moral evil? No, because nothing has been lost.

Suppose I destroy the timeline, and restart from an earlier point. Have I committed a moral evil? Very much yes. What was lost? To give only one person's example from Flight of the Navigator out of a planet of billions, out of a whole universe, the younger brother who was left behind had spent years - of personal growth, of creating value and memories - helping his parents with their quixotic search. And then bonding with the new younger "older" brother, rejoicing with his parents, marvelling at the space ship. And then he was erased.

Why do the fuel requirements go up? Where did they come from in the first place?

A time loop amounts to a pocket eternity. How will you power the computer? Drop a sun in there, pick out a brown dwarf. That gives you maybe ten billion years of compute time, which isn't much.

I was thinking of something smaller-- I don't see people talking about a social group or organization which was both diverse and safe (or perhaps even just reliably safe for non-privileged people), even if it was just for a short but extraordinary period.

And as for weirdtopia, in some ways we're already there. It took me three or four years to stop thinking that having gay marriage as a serious political issue wasn't something out of 1950s satirical science fiction. I was never opposed to it, just surprised that it ever got on the agenda.

Yes, I remember when as a teen I first read Diane Duane's "Door into..." series and found it a beautiful idea, but completely implausible, that a woman could have a wife. And yet it happened. And it isn't a tenth of the way to what a world would be like without patriarchy.

Let me put it this way - I think that the endpoint would be a culture that doesn't even socially mark sex as a category, treating it as (in any given pair of a mated group) "biologically compatible as-is" or "biologically compatible with medical help" (such as stem cell gametes, in-vitro organ-printed wombs, etc) that latter encompassing both homogamete and infertile pairs, that does mark gender identity but doesn't assume there are only two nor does it correlate them with gametes, and in which clothing style, or femme versus butch, doesn't correlate either with either gametes or gender identity.

Scott Aaronson showed that time loop logic collapses PSPACE to polynomial time.

It replaces the exponential time requirement with an exactly analogous exponential MTBF reliability requirement. I'm surprised by how infrequently this is pointed out in such discussions, since it seems to me rather important.

And fuel requirements too, for similar reasons.

I agree that what gets foregrounded matters, and that people can learn to foreground different things. Furthermore, I know by experience that the current feminist and anti-racist material I've read has cranked up my sensitivity, and not always in ways that I like.

One thing that concerns me about anti-racism/feminism is that people who support them don't seem to have a vision of what success would be like. (I've asked groups a couple of times, and no one did. One person even apologized for my getting the impression that she might have such a vision.)

However, it's not obvious to me that it's impossible to raise the level of comfort that people have with each other. The same dynamics isn't identical to the same total ill effect.

I'm hoping that the current high-friction approach will lead to the invention of better methods. I'm pretty sure that a major contributor to the current difficulties is that there is no reliable method of enabling people to become less prejudiced. I've wondered whether reshaping implicit association tests into video games would help.

I'm very grateful to LW for being a place where it seems safe to me to raise these concerns.

As someone who cares about anti-sexism and anti-racism, I actually agree that few people can describe the end state of eliminating them. I have difficulty myself. The reason I have difficulty is that sexism and racism are both utterly stonking huge things that distort this culture like an elephant sitting on a soccer ball. What that means is that a world with no trace of patriarchy and no trace of white supremacy would be a "wierdtopia". Even for those who wanted it, it would be culture shock on the order of a 15th century samurai class retainer suddenly transported to contemporary New York. Feminism is slowed by feminists dragging their feet. Anti-racism is slowed by anti-racists who shy away from how much wealth and resources and control of the future they'd have to give back.

Are the specific examples that JulianMorrison gave things that are statistically true about girls versus boys. Is it statistically true that girls don't climb trees? (I'm a girl, and tree climbing is awesome!)

Also, there's a difference between what you're talking about (using probability to predict behaviour when you know nothing else about others) and ways to raise children, since parents in part determine the future behaviour of their children. Even if it is statistically true, right now, that girls don't wear Spider-Man suits as often as boys, and get upset rather than angry, I don't think those states are the ideal world states. Treating your children like these stereotypes are true might be a self fulfilling prophecy.

Note that there are some examples that I think would be true. I do think that, on average, girls are more likely to get upset than angry when in a situation of conflict. But not always: I get upset more often, my brother gets angry, my sister gets angry, my dad gets upset. I do think that the average boy, if given a Barbie, is more likely to re-enact battles with it than dress it. But that doesn't mean it's a good parenting strategy to yell at your son because he's an outlier who likes to dress Barbies. (From a purely predictive view, you could probably make a boy happier by giving him something other than a Barbie for his birthday, but that's if you're not the parent and your actions aren't influencing his future preferences.)

BTW, by "assuming girls are upset where they'd assume boys are angry" I am referring to unconscious fact judgements about infants too young to verbalize the problem. (Cite: "pink brain blue brain" by Lise Eliot). Macho emotions are attributed to babies in who appear male and gentle ones to babies who appear female. Since baby sex is almost unmarked, that means going by the colour of the clothes. (And google "baby Storm" for an example of adults panicking and pillorying the parents if the cues that allow them to gender the baby are intentionally witheld.)
