As technology marches on, some people get trapped using decades-old software and devices. Here's a look inside the strange, stubborn world of obsolete Windows machines.
Software is never without bugs. Baffling you’d say otherwise. And I was referring to the many situations where companies used outdated computer systems for many years even though it causes extra work for employees. Absolutely textbook tech debt.
Absolutely disagree on this. There is no fundamental reason software must have bugs. However old systems can be their own technical debt because of things like the hardware no longer being produced and therefore unable to be directly repaired if it breaks from age.
This leaves either reprogramming for a modern device or things like emulation which can create/surface bugs that weren’t present before.
The most extreme example I have heard of (sadly couldn’t quickly find a link for it) was a disorientation simulator for pilot training that had zero software issues in several decades of use and when the hardware failed they replaced it with an FPGA in a modern system that ran all the old code 1 for 1. PDP stuff originally I think.
Additional edit - I’ll add that “bug free” software is insanely rare in reality and nearly but not quite impossible to create in practice. I can’t say the software didn’t technically have bugs but if multiple decades of use didn’t have them show up in practice it is functionally bug free.
Spending effort and money to upgrade a system just so you can say it’s new makes no sense.
Physical security systems still use single-pair lines for door switches because it just works. There’s no reason to make those things networked just because you can (and companies are trying).
Your kitchen knife is not a computer.

You make a fair point.
It’s always a risk balance.
