I think this is kind of sad, but I guess I'm also very fortunate in who ( most of ) my employers have been. I've spent a large portion of my career working in codebases alongside stuff from the '90s, and with my first employer the things I was doing ~20 years ago are still in production systems today, right there alongside the older bits from the '90s in many cases. I saw some comments in code last week from the founders of my current employer, written back in the '90s when I would've just been entering high school. That code and much more is still there in a product used and beloved by millions. At an employer in the middle there, the oldest code was from the mid-2000s but it's still kicking around. Code I wrote there a decade later is still in production use today. I can only think of a single employer where this isn't the case and it was a shitty startup that I never should've accepted an offer for.
