some aspects of programming have really been made obsolete

I'd agree that some specifics have been made obsolete. Some habits and routines are currently being ignored or skipped, but the amount of skill that's gone away is very small.

As mentioned before, we downsized brutally after Y2K. The people most affected were the highest-paid who weren't the best code-grinders, and these were the documenters, the programme people, and the mentor types. We lost our guides, our structure, and our historians. We've been growing again like feral children rebuilding society from the wasteland like it's Mad Max, and there's a LOT of the Why that we either don't know, that we ignore, or that we skip in the interests of (insert manufactured urgency here).

We are re-learning some of the whys, but we haven't yet seen the half-assedry chickens come home to roost on that. The symptoms are there: Boeing's Gilligan's Island in Space, supply-chain sploits in waves, personal information lost weekly, all these things that are clipboard hassles we stopped doing that pelrevent massively expensive things later.

Crowdstrike may die now, mainly because they were marauding leopards we allowed to eat our face. Solarwinds before that, same issue but they seem to be okay. There are dozens of ohShit moments that could lead to similarly preventable problems, that we knew not to do ... once.

Well get there again but we'll be rediscovering a lot of what some techbro will claim is obsolete, old-practice, too-cautious, hand-wringing in our neu and moderne go-hard/break-lives paradigm.
