I don't know about chess, though earlier computers didn't have the power, so people could've reasonably said that.
But we certainly saw it with Go. Many people said that a computer could beat a person at chess or checkers, because they were simple, limited games, but Go was too complicated, too many possible combinations. A computer could never beat a Go champion. And here we are, with multiple generations of AlphaGo pushing the boundaries. They might use a couple thousand CPUs and a few hundred GPUs, but they can do the impossible thing.
* Using the algorithms they used to beat humans at chess.
I were there during those discussions, the AI optimists argued that since computers could beat humans at chess GAI would soon be here. Then it is reasonable to argue that even a simple game like GO is impossible to solve the way we solved chess, so there needs to be more fundamental breakthroughs before GAI can happen.
That same thing is playing out today, and the AI proponents are still misunderstanding the other sides argument. The argument isn't "computers can never do this", the argument is "the algorithms and methods we use today can't do this, so there is no clear path to intelligence from where we are".
