I should have clarified that I think (or at least I thought so, prior to your question; kind of confused now) Yudkowsky’s answer is probably one of those two MIRI responses. Sorry about that.
I recall you or somebody else at MIRI once wrote something along the lines that most of MIRI researchers don’t actually believe that p(doom) is extremely high, like >90% doom. Then, in the linked post, there is a comment from someone who marked themselves both as a technical safety and strategy researcher and who gave 0.98, 0.96 on your questions. The style/content of the comment struck me as something Yudkowsky would have written.
Okay, this is very off-topic, but I just really want more EAs know about a browser extension that has massively improved my Twitter experience.
