He was half-wrong about the specific methods used (I say half-wrong because half of AlphaGo relies on relatively-brute-force MCTS). I don't think this detracts from my point - it is hard for any researcher to predict the exact methods that will be used a decade from now.
You tried to use one expert as a refutation of my claim that there was a general consensus with how long it would take for computers to beat a human in Go.
A simple search on google will provide you with plenty of writing backing that sentiment up.
Asking any of your friends who took AI classes back then would confirm the same.
