It's great to discuss ways to improve things, but that is different than suggesting that the whole thing is rotten to the core and needs a re-work from the ground up. The productive way to do this is to identify specific deficiencies and propose targeted incremental improvements to address them. This is what all the people involved in various standards and implementations on the web have been doing for years. This is working, progress is just slow and difficult, as it is with most things that are worth doing.
