it does seem like FAI has a special attraction for armchair rationalists: it's the rare heroic act that can be accomplished without ever confronting reality.

After all, if you want to save the planet from an asteroid, you have to do a lot of work! You have to build stuff and test it and just generally solve a lot of gritty engineering problems. But if you want to save the planet from AI, you can conveniently do the whole thing without getting out of bed.

What? really? I happen to have drunk the kool-aid and think this is an important problem. So it is very important to me that you tell me how it is I could solve FAI without doing any real work.
