As someone else has pointed out about themselves, I'm a battle-scarred, wizened, grumpy old man, with over 35 years of coding behind me (and still going strong. My latest checkin was about five minutes ago. I'm taking a quick HN break, before tying a bow on the project for the evening).
I've come to learn that not all new stuff is good, and not all old stuff is bad. I still use techniques and habits that I picked up, in my very earliest, Devonian Dev days, but I also really like some of the newer stuff; much of it only available, because of the advances in tooling and teaching.
I've also learned not to give a rat's ass whether or not people are impressed by me. The ones that matter, are, and the ones that aren't, seldom matter.
A lot of my programming is a hideous chimera of techniques, mashed together, and simmered at a low boil. It's a scary place.
Works well, though.
