I agree with the overall conclusion but there are a few minor points that could be corrected:
① Watson doesn't play chess as far as I know.
② The last version of AlphaGo ("Zero") doesn't use any historic game logs. Starting from the rules and playing against itself it surpasses the previous version in just three days which is not general AI but still very impressive.


Tore: Thanks for the correction. Yes of course Watson is famous for the Jeopardy game. Point 2 is so new that I don't have an opinion yet. If it does not use any historic game logs, how would it learn human playing patterns? Also, I'm not sure about the applicability to other problems which cannot be reduced to a set of rules.
