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.
I disagree, currently a human guiding an AI agent is far better (more productive for less money) than an AI agent with very loose non-technical guidance and The Ralph Wiggum Loop.
I don't know how much longer humans have, but I don't think they can be cut out of the loop entirely just yet.
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).
When you factor in overhead and benefits, many companies were regularly paying that much for someone (many someones) to "read this Jira ticket and implement the feature".
We are currently in the "centaur" phase where a human-AI combination produces the best output, but I think some people are betting on the fact that the AI only product will eventually outperform the centaur. And with the cost of tokens falling thanks to fierce competition from the Chinese open weight models, it's definitely possible that those that bet on AI early will reap payoffs in lower expenditures for more output.
Honestly not sure which side I land on that bet but I definitely can't rule it out.
