I am not myself particularly concerned with the Friendly AI problem. I think it’s good and necessary that others are working on it, and I’m glad at least one of them is as bright as Eliezer. That makes one less thing for me to worry about.
That doesn't make much sense. It seems pretty obvious that, although he's smart, Eliezer isn't capable of solving Friendly AI single-handedly, and the amount of resources being devoted to it is much smaller than anyone who accepts that UFAI is a threat should want.
Edit: Ok, yes, there exist reasons for Eric Raymond not to devote attention to Friendly AI other than Friendly AI not needing more attention devoted to it.
Unless you think UFAI is a problem so large that all others are irrelevant, there's room for people to work on other problems justifiably.
