I am a previous PhD student who worked under Marvin Minsky, and I do believe that there is no evidence that Minsky was present for any sexual misconduct, and some of the quotes about Minksy do not mention that there is no evidence of Minsky's sexual misconduct. I believe the quotes about Minsky unfairly harm Minsky's reputation.
Again, this is great work, and I'm mostly nitpicking from my very particular perspective as someone who has worked directly under Minsky.
