I'm not speaking for SIAI as this is more of a Visiting Fellows thing than an SIAI thing, but there are people working on Friendliness, and creating a Friendliness roadmap. We have lists of hundreds of problems, and lists of potentially relevant fields or concepts.

Meh. Now I'm a bit annoyed in that I did try to poke people into a direction where they'd do something like that when I was there as a Visiting Fellow, but mostly the reaction seemed to be "we should leave all thinking about Friendliness to Eliezer". But upon reflection, I realize that I may not have been as vocal about that as I thought I was (illusion of transparency and all that), so I guess I only have myself to blame for you guys only starting on all the real interesting stuff after I left. ;p
