I am coming to this late as I'm just now catching up on recent Less Wrong posts. I am really surprised and happy to read this post, because it is unusual and pleasant for me to upwardly revise my opinion of someone so markedly. I'd seen your previous writing on LessWrong and decided, in a blunt emotivist summary: boo multifoliaterose. This post has reversed that opinion.

I have a question somewhat similar to something jimrandomh brought up - there was a passage in this post that indicated that you might have significantly changed your opinion of Yudkowsky and of SIAI overall, though you didn't really explore it in detail:

I had been unaware of some of the activities which SIAI staff have been engaging in; activities which I judge to have significant positive expected value. I had also misinterpreted some of SIAI's policies in ways that made them look worse than they now appear to me to be.

I'd like to read more about this, if your opinion has changed significantly/interestingly.
