Such naïveté. The much more likely scenario is that AI is used to add or replace ads in a website in a way that's now impossible to remove. Running your own AI on the browser will be disallowed to "ensure a safe browsing experience".

I wonder how far we are away from AI being required to link to the TPM in a way that the OS and hardware people can have full authority on what you can use.

We're not that far off. But it will not just be for AI, but all software. Mobile OSes has already normalized the expectation that you don't control what can run on your own devices.
