I’m not sure about that. There’s a lot of runway left for obstacles that are easy for humans and hard/impossible for AI, such as direct manipulation puzzles. (AI models have latency that would be impossible to mask.) On the other hand, a11y needs do limit what can be lawfully deployed…

That's irrelevant. Humans totally hate CAPTCHAs and they are an accessibility and cultural nightmare. Just forget about them. Forget about making better ones, forget about what AI can and can't do. We moved on from CAPTCHAs for all those reasons. Everyone else needs to.
OK, what you now call turnstyle. If I get one of those screens I just close the tab rather than wait several seconds for the algorithm to run and give me a green checkbox to proceed.
Totally different type of latency. A person with a motor disability dragging a puzzle piece with their finger will look very different from an AI model being called frame by frame.
