I think simply telling web developers to "do more" is not the end of wisdom here.
What would be best is if browsers offered a "deaf mode" or "blind mode". I suppose the deaf mode would simply be turning the sound off but I'm probably missing something and that's my point here: It's hard to design for accessibility because I don't even have the proper means to test like a disabled end user would test the site. What would be best is if in a "blind mode" Chrome would make every text too blurry to read and I can only read things if used like a blind person would use it, possibly with a screen reader. Right now all we have are numbers telling us our accessibility score and I think even for that we need to use separate tooling.
