> Isn't that framing what the sentiment used to be towards computers playing Go,
No. I was a student in the mid-90s, and the position of everyone regarding Go was "We'll have enough compute power one day".
It was only after AlphaGo hit the news with its wins that I started seeing this revisionist history of "They said the computer will never win at Go".
To which I have to reply "No. They did not".
