… in which case I’m allowed to suddenly remember something in 2017 also 
I still really strongly remember when Nick was having his existential crisis after the emergence of AlphaGo .
“Everything I have taught you is wrong”.
I also remember OGS starting to come to drips with AI play, notably 3-3 invasion, at that same time (and that video was mentioned in that thread, so it’s kind of the same memory).
(OK I cop a couple of months negative points, but it was worth it).
