That hardly makes any sense. Most widely used frameworks are open source projects; it seems much more reasonable to assume that constant changes in direction are more an expression of developers wanting to play with the fancy new toys instead of sticking with one paradigm and keeping it stable.

Even setting that aside, there's nothing keeping older developers from switching to a newer technology; it might be a bit bothersome to adapt to ultimately inconsequential changes again and again, but that applies to younger devs just as much.

It's also not like web development is old tech in any way. There's constant improvements being made and things are often changing for the better.

Well, for the most part at least. Looking at the situation with serverside resource compilation I have to wonder when the world of web will re-invent make and call it a revolutionary achievement.
