I solve problems. My experience in problem solving will never become irrelevant. It happens that I solve problems with code. With my experience in problem solving, I can pick up "new tech" quickly-- primarily because there's really nothing new. Things get smaller and faster; the real technological advancements are in the physics of storage and processing. The "advances" in software seem to follow what The Graybeards Of Antiquity dreamed up in the 1960s, now with a slicker, graphically enhanced user interface.

I see so many less experienced software creators going nuts over something "new" when it's just repackaged from a decade (or three decades) ago. It's interesting to see reactions when asked "how's that different from Q?" or "but what about problem J?" and even "ah, that's over here in TAOCP ... you know Knuth, right?"

EDIT: relevant quote from another headline on HN-- 'Calling a hierarchical directory a "folder" doesn't change its nature any more than calling a prison guard a "counselor".'
