As a handicapped person: The internet is my accessibility.
Most of the standard conviences available to "normal" people because smartphones are a thing and yadda is how I make my life work.
Among other things, I also co-own a tiny list for blind developers. So I have some familiarity with the fact that there are people who actually need accessible design in a way that I don't.
But I think any internet that works well dramatically improves life for the vast majority of the 60 percent of people who have varying degrees of impairment, two-thirds of whom do not self identify as disabled or handicapped.
