Our window of compatibility only seems to grow larger over time. Old systems mostly get replaced when they lose function or the replacement becomes cheaper. But the replacement usually expects to last slightly longer than what its replacing. We've seen this slowly creep up in home computers, phones and even servers. I would argue that this is a function of small incremental improvements in everything from hard drives to computing.
Lots of designs from the past can no longer connect to the internet in a meaningfull capacity but new hardware today might meaningfully last far longer than the developers could even anticipate.
