People are trying to "fix" the web, when it should be replaced or redesigned. Thus problem is human, not technical. Whom should decide what replaces all the TLA that is required for the "modern" web? Too much time and money is invested in browsers, servers, languages, frameworks, training, tools etc...

Not that's all bad. A lot of technology that wouldn't have been developed, has been. It's changed a lot since I started building sites in '94. But I still can build nicer apps for the desktop, with better interfaces, better performance using a single programming language faster than I can develop "rough" equivalent web application.
