Web development is the absolute worst at this. None of the technology is new, whatsoever (mostly stealing from Lisp, rebranding it, and doing it wrong or calling MVC by yet-another name). It's impossible to quantitatively state that the new tools we use today are any better than the tools we just tossed out yesterday. Because no one became a master at the tools of yesterday. There is no basis for comparison. No expertise. Just the eternal trend following.
