Roko's related ideas;

I've criticised CEV from several directions. It seems technically and politically infeasible to me. The CEV documents mostly read like wishlists for those seeking funding from some kind of benevolent communist government, whose leader is into science fiction.

However, I haven't collected my thoughts on the topic together in one place. I figure I should probably save my energy in this area, until there is something less out-of-date, and more concrete to consider.
