Frankly, I believe it's that we're working at the wrong level of abstraction. High-level of abstraction is good – and it's good that there are several competing high-level abstractions. That's exactly what happens in desktop programming, e.g. you typically don't use the same languages for UI development, games, scientific processing, etc. But one of my points is that we definitely haven't reached this level of maturity on the web.
