That’s the game plan for the AI companies: once companies have massive codebases of critical AI generated code and a skeleton crew of prompt engineers they’re going to be locked in to the AI product to develop anything new.
They’re not even selling shovels, they’re selling subscriptions for shovels.
I don't think there needs to be any intentional evil scheme for this dynamic to be worth considering and mitigating.
For example, there's also no cabal behind memory prices dropping (ignoring the development of the past months, of course), which in turn enabled web and game developers to use more memory and make their software non-viable on older devices.
