After 34 years in software development, I'm beginning to wonder if being "left behind" might in fact be the secret to a long career.

@jasongorman C in 1986, ksh/sh/bash by 1992, Verilog in 2001. Kept finding jobs that needed nothing more than that.

A pal of mine picked up COBOL in the 90s and that saw her through to her retirement this year.
