One thing we missed (which I won’t go back for) is the start of the Images of Olden Times and Images of Newer Times threads, both in October 2017.
I remember when AlphaGo Master played its sixty games against professionals on Tygem and Fox, from December 2016 to January 2017 (we’ll take the ending date).
See Redmond’s AlphaGo vs the World series.
