Here's the crux of our disagreement. You believe that the web is such a broken application platform that it is possible to convince enough vendors and people to get behind a better solution. However, I (despite your presumptuous implication that I'm a millenial), have been around long enough to know that will never happen. Web standards will continue iterating, and companies will continue building apps on the web, even the most powerful app platforms today such as iOS and Android for all their market power can not stop this force. The reason is because it's a platform that works. The man-millenia behind the web can not be reproduced and focused into a single organized effort. You might as well argue that we replace Linux with Plan 9, it doesn't matter how much passion you have and how sound your technical argument is, Linux, like the web, is entrenched. It's gone beyond the agency of individual humans and organizations to become an emergent effect.
That's not to say that the web might not some be supplanted by something better, but it won't come because of angry engineers wringing their hands about how terrible the web is. It will come from something unexpected that solves a different problem, but in a much simpler and more elegant way, and over time it will be the thin edge of the wedge where it evolves and develops into a web killer.
Maybe I'm just cynical and lack vision, perhaps you can go start a movement to prove me wrong. I'll happily eat my hat and rejoice at your accomplishments when that time comes.
