This is a fallacy of aging developers. Sure, some concepts resurface, but the same way you can't step in the same river twice, things are never the "same". One example would be functional programming - sure, the concept was there since the 50s, but what did they use it for? What was the ecosystem? How did the functional aspect affect the tooling, the libraries? In these terms, FE itself is not revolutionary, using it in certain contexts, and with certain frameworks it is.
