Old things weren't cost cut to death.

When it comes to keyboards specifically, higher quality keyboards where more standard. Even outside of Model Ms I have a Dell keyboard with ALPS switches and it's head and shoulders better made than anything Dell is willing to supply now.
Granted those keyboards where much more expensive than the $5 chiclet shit you get with PCs now but modern cost cutting infects everything.

You could spend $300 on a keyboard and it's no more reliable than a $50 one and it's because the things that go inside the $50 keyboard like the electronics, PCB and SMT process are going to be nearly the same thing going into the $300 KB. It ends up just being the nature of modern electronics manufacturing which is inherently cost cut.

Old keyboards are just built differently, you can debate all you want if a modern keyboard is or isn't more reliable than a model M (considering I just repaired a model m) but the inherent nature of companies not looking to cut out every penny leaves you with a product that feels more robust and different.
The fact there are surviving examples after 30+ years only leads more people to a conclusion something is more durable and to be fair there is a level of quality necessary just to age out that long regardless of use.
