Well, I mean more specific case. FAI approach, among other things, presupposes that building FAI is very hard and in the meantime it is better to divert random people from AGI to specialized problem-solving CS fields. Or into game theory / decision theory.
Superficially, he references some things that are reasonable; he also implies some other things that are considered too hard to estimate (and so unreliable) on LessWrong.
If someone tries to make sense of it, she either builds a sensible decision theory out of these references (not entirely excluded), follows the references to find both FAI and game-theoretical results that may be useful, or fails to make any sense (the suppression case I mentioned) and decides that AGI is a freak field.
FAI approach
Talk of "approaches" in AI has a similar insidious effect to that of "-ism"s of philosophy, compartmentalizing (motivation for) projects from the rest of the field.
