>I think chess does possess the potential to develop and train the strategic thinking skills of players
Chess was a big meme for decades in computer science, but what has come out of that aside from programs that are good at Chess? There was a lot speculation that coming up with programs that are good at Chess would somehow help with coming up with programs that are good at solving other problems. But can you give a single example for that? (In the USSR Mikhail Botvinnik shilled for that real-world connection and had nothing to show in the end.)
People who are relly good at Chess who start playing Go are much better at it right from the start than other noobs for some reason, even though in terms of programming a player it's extremely different from Chess.
Do bikes and cars make running competitions meaningless? Besides, there is the issue that some AIs are basically a black box even to the programmer, so that it's a mystery to explain how it makes its decisions. (At least for picture classification there is an approach that generates a heatmap picture that tells you which pixels in the original were regarded by the AI as strongly supporting the classification it chose in the end. For example, a picture with a train might show that the AI heavily relied on the rails and not the actual train to make the right call.)
