The popularity of clean slates

Sometimes I wonder if new frameworks become popular because it's easier to follow the natural progression of them as they evolve rather than trying to catch up with something that has been accumulating over perhaps decades.

If so, then it should be possible to predict the coming of a new system by observing how difficult it is for beginner to break into the established one.

It would be like water building up in a dam, and the a new system will breach it and ride it like a wave.

People experienced in the previous system will be like:

What's all the fuzz about? There's nothing new here! We can do all this. And better! We solved these problems that you are now having 15 years ago!
