But what about when you get old and wrinkled, and you haven't optimized time for learning skills? You will be deserted, won't you?

I am already old and wrinkled youngster. Most skills that are required these days are just the latest new fad and will be forgotten about in a couple of years anyway.

This is true. Everything new technology seems like an evolutionary improvement on one or a few aspects of programming, like separation of concerns, expressiveness, correctness, etc. None of these things should surprise anyone unless they've been stuck in one of the 1990s 3.5GLs and never learned anything else.
