Only if you think skill in chess translates to actual intelligence. As a chess master, I tend to benefit from this myth, but it’s bogus.

The idea that computer chess is a stepping stone to common sense AGI is also fairly absurd to me.

Don’t get me wrong. Leela is a great project. Just see it for it is, an impressive demo showing how machine learning algs paired with massive compute has led to increased performance in a perfect-information game like chess. It’s not a “nail in the coffin” of anything other than possibly Stockfish’s reign as strongest chess player. No more, no less.
