"zomg new framework, I have to LEARN again :("
The problem isn't that you have to learn another framework (although it does become a problem when they're all slightly similar and they start to meld together after the umphteenth, not to mention that learning slows down with age). The problem is that each frameworks brings along new edge cases, new problems and forces you to reinvent tools you already had for this new framework. Although learning new shit can be exiting, at some point, you gotta stick to something for a while so you can also actually build a lasting product with it, rather than building a new prototype but never finishing anything because you're distracted by a new shiny.
I'm sure glad we're advancing beyond the abstractions we have in, say, Cocoa development (which is evolving as well). Seems incredibly selfish to suggest that everyone is incompetent and nothing new is good because you don't want to have to learn new things.
Yet somehow HNers convince themselves that it's scathing sociotechnological criticism of an ecosystem because we tolerate it for some reason. Meanwhile everyone would roll their eyes if you suggested something like "ugh, Objective-C replaced by Swift is like watching Apple read old books."

Even if there were no reason at all, the bias toward writing things ourselves ensures that we'd continue to see these new frameworks.
