It is frustrating that instead of fixing existing, fairly simple interfaces, web tech seems to instead create complicated and harder to use interfaces which are more likely to be used incorrectly or at least inconsistently. It feels like it's likely to make the problem worse, not better, in the long run.

(like, even if it was spelt differently due to backwards compatibility, it would be nice to just have a 'insert tooltip text here' interface that did work on desktop, mobile, and in screen readers. This doesn't feel like it's beyond the wit of man)
