This is precisely why trying to avoid exponentially-long compute times for PSPACE problems through the use of a time machine requires a computer with exponentially high MTBF.

Why exponentially, precisely?

Of course, there's no reason to strictly believe that what you thought was a future version of yourself wasn't either lying or a simulacrum of some kind, or that any note you receive after intending to send a note back to yourself hasn't been intercepted and subverted.

Which leads to interesting stories when those expectations are subverted, but only after they've been established.

True! That's why every twelve-year-old establishes elaborate passphrases for identifying alternate / time-displaced selves.

This is the standard model of time travel / prophecy in Greek myths, isn't it? Maybe I'm overgeneralizing from Cassandra.

[edit] Eliezer calls it Stable Time Loops, which is a term I've seen before.

My understanding is that Stable Time Loops work differently: basically, the universe progresses in such a way that any and all time traveling makes sense and is consistent with the observed past. Under the above model, you will never witness another copy of yourself traveling from the future, though you might witness another copy of yourself traveling from an alternate past future that will now never have been. With STL, you can totally witness a copy of yourself traveling from the future, and you will definitely happen to travel back in time to then and do whatever they did. That's my understanding, at least.

This seems a straw man.He didn't say they where always or often unsuccessful. Just that this can happen. And we clearly do have examples of unsuccessful attempts. See the USSR or the Puritan Colonies in the Americas.

That would have been more reasonable, though also trivial and irrelevant (yes, some reformers fail. what of it? this comment wouldn't make sense in context). But the claim in the great-grandparent is made in absolute terms, a claim about the nature of the world - if you push society from default modes, then it will get harder and harder to accomplish nothing much and eventually you will be crushed.

One might feel compelled to interpret this as an error, and say that the intent was to say something trivial instead of wrong. But I thought that unlikely based on the user's posts in this topic: one about how reformers are crushed by history, one about how "the PC hive mind" is trying to silence them in order to establish themselves as the unquestioned masters of reality, and one misinterpreting and mocking a post about how you can insult people with facts.

Comments about how one's "opponents" are doomed to horrible violent retribution by the very nature of the universe are not unheard of. See, for example, the Men's Rights Movement, branches of which prophecy a coming time of inevitable violent revolution against our feminist overlords, or Communism, under some versions of which the success of the movement and the overthrow of all opposition is an (eventual) immutable fact.

My bad! Probably just oversensitive because of what thread we're in. Apologies!

You happen to know, experimentally, that beings with a high EQ tend to commit actions that decrease general utility in the population whose utility you care about.

You know a lot more than that. You know that they go to different afterlives than Good or Neutral beings, that they can be affected by different spells and abilities, and that depending on their class their own abilities might be affected by their evilness.

A moral theory that supports the eradication of Evil beings need not be utilitarian. I don't think a conventional paladin would function as a utilitarian, for example.

Comment author: TorqueDrifter 28 November 2012 01:00:10AM 0 points [-]

And these afterlives tend to be less pleasant, as I understand it. As an added wrinkle, there are also Evil energies and spells, for example the energy animating a non-evil undead, or certain spells cast by a non-evil cleric.

Very true. Also, the 'right technology' does not currently exist, and isn't likely to in the next decade.

Social reformers often don't seem to understand that pushing a society far away from 'default' human modes of conduct is a bit like pushing a boulder up an increasingly steep slope - you spend more and more energy fighting just to stay in place, while creating an increasingly dangerous pool of potential energy that acts to oppose your efforts. Push hard enough for long enough, and eventually you get crushed as the boulder rolls back downhill.

Exactly, this is why there haven't been any successful social reforms, and people who try to effect reform are successful at first but lose momentum as the reform gets more and more established before being crushed by powerful historical forces. At least that's the word in my local Baron's court.

So.... your claim is that anyone discussing potentially unpleasant or offensive topics with a woman should take special care to be extra gentle in their delivery, include lots of sympathy and understanding, that sort of thing?

'Extra', of course, being in comparison to what they'd say when having a similar discussion with a man?

Gee, what happened to that whole equality thing?

Comment author: TorqueDrifter 28 November 2012 12:42:13AM *  2 points [-]

This claim does not appear in the post you responded to. There is in fact no gendered language except with reference to a previously-established example (and a brief additional example in which the genders of the interlocutors are not stated).
