Accessibility in the web world is, and always has been, a game of catch-up. That is going to get worse, at least in cycles, rather than better.
That is not indicative of the long-term arc, which is unquestionably toward better accessibility.
I'm not denying that when periods of rapid change in web coding appear, there are corresponding periods of accessibility woes. These days, though, those tend to resolve in favor of accessibility, which was not necessarily the case for decades.
If one goes in knowing this, and accepting it as a simple fact, one can avoid a lot of "gloom and doom" thinking, if not frustration. It's supremely frustrating when what had worked is jettisoned for something that, for the moment, anyway, is inaccessible. Nothing is so constant as change.

The psychology of adultery has been falsified by conventional morals, which assume, in monogamous countries, that attraction to one person cannot co-exist with a serious affection for another. Everybody knows that this is untrue. . .
