We picked the wrong century to quit learning ;)

I would feel more inclined to continue to "learn" (read: pick up shiny new frameworks, not actually learn new fundamentals) if the new stuff wasn't just rehashed old stuff. If I need to pick something up, fine, that's trivial, but "learning" for the sake of "learning" is best left to the juniors.

I tell them the truth: I wanna go deep in my stack (Ruby) to the point of learning C and VMs to understand how the Ruby interpreter works. This is what interests me; I really can't see how learning Node or Elixir is gonna make a better programmer than what I want to do.
