I can't make sense of your comment. Firstly because of the obvious massive over-build of GPU infrastructure the AI companies are engaging in. Secondly because the instance of the LLM in the data centre that users interact with is only a small part of the story. The training phase is clearly prohibitively expensive, thus the fact that these things have no way to learn from experience except by smoke and mirrors.
Also your comment feels like the classic climate denial discourse - say something a bit complicated and a bit difficult to follow that looks at a very small out of context part of the story to cast doubt.
