Was that before or after the computer won? :)
The words were uttered long before computers became so strong at chess. But I’ve noticed that computers sometimes get things wrong in long analysis too.
Chess has always been a leading area in “artificial intelligence” (AI). Chess playing programs are very, very strong. Yet they display no intelligence! Here are a few examples.
People correctly realize that if you repeat an position (in all respects), the evaluation of the position is unchanged. Sometimes computers think otherwise. They plan to repeat a position so as to push a problem beyond the computer’s planning horizon.
Computers don’t understand “initiative” or “attack,” only believing their consequences when they see their consequences.
I once had a “fortress” position against a strong computer program. The computer thought it had an advantage, but had no way to break down the fortress. We continued on for many moves to no effect. A person would have learned from its failure to make progress. The computer never learned.
Computers do compute and very fast too. I was once analyzing alongside a computer and noticed that it had considered millions of positions in our minutes of simultaneous analysis. I’ve probably not considered a million positions in my lifetime!
