Y2K wasn’t entirely fear mongering horse shit. There were quite a few important cogs in our digital infrastructure that were using code that would not work past 1999. It was necessary to terrify corporate ownership into paying to fix the code, otherwise there would have never done it.
I mean, that’s exactly what programmers in the '70s thought. That there would be no way in hell that their crap code would still be in use going onto 2000.
Thing is, copy/paste is always going to be easier than writing new code and that’s only going to get worse as chat bots start coding for us.
