That Eliezer Yudkowsky (the SIAI) is the right and only person who should be leading, respectively institution that should be working, to soften the above.

That's just a weird claim. When Richard Posner or David Chalmers does writing in the area SIAI folk cheer, not boo. And I don't know anyone at SIAI who thinks that the Future of Humanity Institute's work in the area isn't a tremendously good thing.

Likewise, Lesswrong (then Overcoming bias) is just the only place I've found that actually looked at the morality problem is a non-obviously wrong way.

Have you looked into the philosophical literature?
