Used to work with UNIX servers in the early 2000s but out of that sector for coming up on two decades -- are z/OS, AIX and HPUX (and other old big iron enterprisey UNIXen) still around? I would have thought that Linux had killed them all of by now. Excuse my ignorance!

They definitely are, not all though, HP-UX is on life support.

However Aix, Solaris (and Open Solaris derivatives), z/OS, IBM i (AS/400), ClearPath MCP, OS 2200, are still being updated and sold.

That list is not only UNIX systems.

Exactly. They exist but just barely.

Enough to pay salaries of those making them go.

Enough to pay the salaries of those keeping them on life support, more like. I wouldn’t say they are going anywhere. To be clear, that doesn’t mean they are going to die anytime soon. Mainframes are still around and getting refreshed and upgraded, too.
