I don't think anyone's "making money" yet. We have a race to build up hardware for AI, and one to train models. There are some profits in there, but who's making money from the work AI performs? Nobody, because any advantage some company claims with AI is quickly replicated by competitors and profit dries up.

Today you can put a coding agent to migrate an existing application to another language (like chardet). Even if you don't have the code, if you can run the app you can still clone it, using it as an oracle for replication. That is why there will be very little profits in AI usage.
