Nope, we still have an IBM i deployment kicking around at $DAYJOB, it's running natively on POWER hardware. Way back in the days of the original OS/400 running on AS/400 hardware, IBM had the foresight to have applications compile to MI (Machine Interface) code; which is a bytecode format closer to something like LLVM IR instead of something like JVM or CLR bytecode. When a PGM object is copied or created on an IBM i system, TIMI (Technology Independent Machine Interface) takes the MI code and translates it to a native executable for the underlying platform.
We probably still have a couple of PGM objects kicking around on our modern POWER hardware that were originally compiled on an old AS/400 system, but they run as native 64-bit POWER code like everything else on the machine.
The IBM midrange line gets a lot of undue disgust these days, it's not sexy by any means, sure, but just like anything running on modern day Z/OS you know that anything you write for it is going to continue to run decades down the line. Well, as long as you limit the amount of stuff you have running on 'modern' languages; because Java, Node, Python, Ruby, etc. are all going to need upgrades while anything written in 'native' languages (RPG, COBOL, C/C++, CL) compiles right down to MI and will keep working forever without changes.
In some ways the IBM mainframe line is an amazing piece of engineering. My understanding is that the emulation layers can even emulate hardware bugs/issues from specific lines of long-dead equipment so that ancient code (that was written to take these issues in mind) will still function as expected.
