Don't choose hamster-wheel career tracks in the first place. Try to find Lindy paths [1], [2]. For example, SQL experts and DBAs. The rise and (mostly) demise of NoSQL actually cemented SQL's reputation as an irreplaceable technology. The latest Web framework is by definition non-Lindy: it's the new kid in town who think they know it all. grep is lindy, Unix is lindy, the qwerty keyboard is lindy, C++ is lindy, Computer Science is lindy, algorithms and data structures are lindy. Knowledge of the real world, whether it be finance or shipping, is lindy. Sorry, verbose reply, but I hope it helps.
