Is there any reason to use VMS today other than for existing applications that cannot be migrated? I've heard its reliability is legendary, but I've never tried it myself. The 1 year licensed VM seems excessively annoying. Is it just old and esoteric, or does it still have practical use? At least with Linux, multiple vendors release and support distros and it is mainstream, whereas with VMS, you'd be stuck with VSI.

There is a pretty good amount of operation-critical stuff like power plants (especially nuclear), radars, traffic management and various finance/insurance/airline services that operate on VMS afaik. Something about very reliable cluster-native operations, or so it would seem. 90's cloud-native.
