One potential virtuous cycle here is that accessibility trees used by tools like screen readers are also a nice potential way for a model to consume information about what's on screen and how it can be interacted with. So it creates an additional incentive for improving the accessibility of new and existing software, because doing that lights up integration with future models.

This cycle starts with an integration for model developers. I wonder if anyone is working on a generic ARIA hookup, as well as whatever standards are necessary for desktop/smartphone integration?
