I agree you’re right in that the current tech stack is bad. But the answer is to fix that, and I think (very) slowly we will.

JS was a terrible language but nowadays it is pretty good in some areas, passable in others, with some horror shows left in. The ecosystem and tooling are the real problems. I don’t understand why these issues haven’t been addressed by Google et al.

Native applications are just so much more expensive to develop and maintain. Given the nuances of different platforms, it’s also very difficult to keep different versions in sync. People expect collaboration as table stakes, which makes that task even harder.

I agree accessibility is a problem.

Ironically the Java applet had the right idea, as a compromise between our positions, but wrong time and maybe wrong language? Its Swiss cheese security didn’t help either.
