Thanks for the summary and repost. I do think that this saga also has lessons for the EA community. I have seen many incidences whereby we overemphasise EA alignment over subject matter expertise , especially when subject expertise is more practical and mission critical, for example in operation and risk management. This supports your comment on ‘This might leave the remaining group less able to identify weaknesses within group beliefs or course-correct, or "steer".
While anecdote is not data, this is my first post in this forum, as someone who does not self identify as EA (though my friend assures me my views are not exclusive of being EA) and has many problems with much of the EA culture.
But I find the criticism of EA based on SBF incredibly annoying and shallow. Like giving up vegetarianism because of Hitler.
So, I didn't evaporate, for what it's worth!
