Lost the source code to your elevator control app? Stuck on OS/2. Guy who wrote it is dead, never used source control, you don’t use it in new installations but those old elevators still have to run and the PC hardware has long died and is irreplaceable? Then you have no choice but call ArcaOS.

I’ve seen more than one place where that scenario or something similar has occurred.

Sure, but you'd think that after 30 years, someone would have completed a migration. ie use Arca as a transition step while you figure out how to get onto something else.

I guess software lifetimes are longer than a generation now, even for PC-class workloads.

You would think so but working software is hard to replace. The last two places I worked for still had code running on DEC VMS!
