I think they were suggesting using AI to audit for accessibility, which is probably a better approach, and probably more effective than a lot of the basic accessibility checkers out there that work on a list of fairly simple rules and don't understand the context of what they're doing, so tend to give either very limited advice, or sometimes even offer bad advice.

Research and fallbacks would certainly be better. An 85% design, 15% algorithmic solution is probably the sweet "pobody's nerfect" spot, but a company using AI to solve accessibility is like selling rape whistles -- in a perfect world, your market is nonexistent.
