As I remark elsewhere in this thread, the point is that I would have expected substantially more nuclear exchange by now than actually happened, and in view of this, I updated in the direction of things being more likely to go well than I would have thought. I'm not saying "the fact that there haven't been nuclear exchanges means that destructive things can't happen."
This pattern seems vanishingly unlikely to save us from unFriendly AI. It would take, at the very least, a much more effective education/propaganda campaign.
I was using the nuclear war thing as one of many outside views, not as direct analogy. The AI situation needs to be analyzed separately — this is only one input.
One open question in AI risk strategy is: Can we trust the world's elite decision-makers (hereafter "elites") to navigate the creation of human-level AI (and beyond) just fine, without the kinds of special efforts that e.g. Bostrom and Yudkowsky think are needed?
Some reasons for concern include:
But if you were trying to argue for hope, you might argue along these lines (presented for the sake of argument; I don't actually endorse this argument):
The basic structure of this 'argument for hope' is due to Carl Shulman, though he doesn't necessarily endorse the details. (Also, it's just a rough argument, and as stated is not deductively valid.)
Personally, I am not very comforted by this argument because:
Obviously, there's a lot more for me to spell out here, and some of it may be unclear. The reason I'm posting these thoughts in such a rough state is so that MIRI can get some help on our research into this question.
In particular, I'd like to know:
