I'm trying to help a dear friend who would like to work on FAI research, to overcome a strong fear that arises when thinking about unfavorable outcomes involving AI. Thinking about either the possibility that he'll die, or the possibility that an x-risk like UFAI will wipe us out, tends to strongly trigger him, leaving him depressed, scared, and sad. Just reading the recent LW article about how a computer beat a professional Go player triggered him quite strongly.

I've suggested trying to desensitize him via gradual exposure; the approach would be similar to the way in which people who are afraid of snakes can lose their fear of snakes by handling rope (which looks like a snake) until handling rope is no longer scary, and then looking at pictures of snakes until such pictures are no longer scary, and then finally handling a snake when they are ready. However, we've been struggling to think of what a sufficiently easy and non-scary first step might be for my friend; everything I've come up with as a first step akin to handling rope has been too scary for him to want to attempt so far.

I don't think that I'll even be able to convince my friend that desensitization training will be worth it at all--he's afraid that the training might trigger him, and leave him in a depression too deep for him to climb out of. At the same time, he's so incredibly nice, and he really wants to help with FAI research, and maybe even work for MIRI in the "unlikely" (according to him) event that he is able to overcome his fears. Are there reasonable alternatives to, say, desensitization therapy? Are there any really easy and non-scary first steps he might be okay with trying if he can be convinced to try desensitization therapy? Is there any other advice that might be helpful to him?
