Well if nothing is changing with the language, or no new frameworks, then that does mean stagnation. Is it a bad thing? Of course not. Such stable languages and tools are great to have.
Likewise I do think the sleuth of frameworks means progress. Not always good progress, but we will continue to learn and improve things going forward as these experiments succeed or fail.
Yea, I'm not saying that the churn is a good thing. But I do think that in 5 years, JS/HTML/CSS will be a truly great interface toolkit because of all the ideas that are being tested now. It is kind of annoying at the moment.
