I actually think that the direct usage of AI will reduce in the system-style group (if it was ever large there).
There is a non-trivial cost in taking apart the AI code to ensure it's correct, even with tests. And I think it's easy to become slower than writing it from scratch.
FWIW, I'm clearly system-style. Given that my current company has an AI product, I'm dogfooding it, and I've found good uses for it, mostly for running quick experiments, as a rubber duck, or for solving simple issues in config files, Makefiles, etc.
It doesn't get to generate much of the code I'm shipping, though.
