Years ago, when he was still in NYC, I posted a minor technical correction under one of his videos on reddit and received a rambling essay-length reply plus an aggressive DM from him about how "people like me" are trying to bring him down, all at ~4am his time. That's not "filtering out what matters" it's evidence of paranoid mania, and that's all I see in his videos now.

I'm glad he's been able to turn this into a career doing genuinely good work that I agree with, but he is first and foremost a drama youtuber and that requires a confrontational personality.
