I think it's an interest hypothesis but I don't think it works out like that. AI prices aren't priced in relation to the work they do, they're priced in relation to tokens (input/output). As long as it's cheaper to use those tokens than it is to pay a dev, then dev salaries will likely fall. Whenever it becomes cheaper to hire a dev than to use AI, a company will likely just hire a dev. But AI prices won't fall just because dev salaries have.
