*Sigh* I'm already an old-timer making my way toward irrelevance
Had a bit of a jolt several years ago that reminded me that skill sets have a "best before" date. In computing, by the time you become comfortable with something, everyone else has moved on.
So I sprint now just to keep up. I'll keep doing so until an uncaring and unkind industry grinds me into a pile of dust (probably by middle of next week or so).
