This is not a silly question, because it's kind of silly:
Has an AI ever actually gone through all of the steps necessary to become a chess master? Go to competitions, raise in the ranks, take a plane to the masters, organize support and all the real life details necessary? Playing chess is just the small formal part here, and all of the obvious things humans obviously do, well...
Chess is a perfect information game with objective, easily measurable outcomes.
Show me a software business that looks like that and I'll agree with your hypothesis.
Otherwise I don't believe your metaphor proves much of anything.
Please never compare perfect information games (https://en.wikipedia.org/wiki/Perfect_information) with actual reality, which is probably many orders of magnitude more complex.
Kind of similar story with math (pure) and other sciences (impure): https://xkcd.com/435/
OpenAI & co keep presenting their achievements at maths competitions as their path to AGI/ASI/singularity. But if you look at that XKCD graph, the way the joke reads is in terms of arrogance (scientists working on purer fields are more arrogant), but the actual science complexity work the exactly the other way around. Impure sciences are orders of magnitude more complex.
Implementing a sorting function = coding (relatively pure).
Creating an entire commercial software product/service with high performance and other professional-level characteristics = software engineering (wildly impure; after 60+ years we can't even agree on the best programming language to use).
