You said it was "considered to be the pinnacle of intelligence" 150 years ago, that is, almost 150 years after calculus was invented, and now you're interpreting that as meaning "a person on the street would think that intelligent." And you said I was moving goalposts?

It is a bad example, but it's a bad example because we could explain the algorithm to somebody in about 5 minutes.

I don't think we disagree. I just think that if chess programs are no more sophisticated now than they were 5 or 10 years ago, then they're poor examples of intelligence.
