I don't much like his "morality as hostile meme-warfare" idea either. In fact, I disagree with almost everything in that post.

What do you mean by "don't like"? It's epistemically wrong, or instrumentally bad to think that way? I'd like to see your reaction to that post in more detail.

And thanks a lot for your critical feedback; it's really helpful given that so few other people come up with useful competent criticism.

It seems to me that people made a lot more competent critical comments when Eliezer was writing his sequences, which makes me think that we've driven out a bunch of competent critics (or they just left naturally and we haven't done enough to recruit replacements).
