Sometimes I swear that people are just making up acronyms here to troll people.

I assume you mean "orders of magnitude" and not "out of memory". I have never seen the former used as an acronym before, let alone without some kind of contextual clue. (In typical Baader-Meinhof fashion, I'm sure I'll see it again in the next 24 hours...)

I have just combined those together. I use astronvim as main editor but when I need IDE I switch to Idea. I use ideavim with configuration as close as possible to astronvim. So text editing is the same for me in both programs. Modal editors are still great and they can do a lot of work that looks like magic for AI era trained developers.

Did Hiro even use a keyboard? I remember everything was VR in Snow Crash.

I, of course, pretend I'm Zero Cool.
