  > Then why don't actual screen readers exist when a.i.'s at this point can practically solve captcha's Training a computer to solve a captcha is a lot easier than training a computer to understand interface conventions. There isn't an AI that can look at a jpeg screenshot of an interface and say, "there's two input elements, and it looks like they're grouped together and control the list to the left of them, and one of them is selected, which I can tell because it has some kind of subtle glow effect on it, but not the glow effect you would get if you moused over it." There's nothing that can realistically do that today, and it wouldn't be fast enough or performant enough for low-powered cell phones and laptops even if it did exist. If you're just looking at describing pictures themselves... sure, Facebook does auto-generate alt tags for images if you forget to put one in. And Youtube auto-generates captions. Those are valuable services, but they have a lot of glitches and mistakes. If you're a blind reader, you'd prefer not to have that experience when you're using a piece of software, you'd prefer something that just works reliably. It's the same reason you probably used a keyboard to type this comment instead of speech to text. Speech to text is useful in some cases, but not good enough or accurate enough that you would want to use it as your main input method.
