Hey... Real Question: How about JAWS (screen reader) software [1] users that are blind / visually disabled? Do those assistant tools count? Can someone do something like control JAWS programatically and navigate website UIs using a robot? It seems possible. I am sure JAWS has a crazy web browser footprint. (I have seen videos at my office where a junior trader was blind and using JAWS on Bloomberg and a trading app. The sound was so fast that it sounded like jibberish... but she could move around super fast.)
