Do you think experience holds better the lower you go down the stack? Part of my frustration with web development - especially front end, is knowledge decays very fast there. I'm fine with learning new stuff but relearning the same thing all the time and losing my edge is a big annoyance. So part of my wanting to move lower down the stack is my belief that my knowledge and experience will hold up better there. So I'm considering either that or moving to backend work writing something like Java which I also perceive to be a very good investment. .
