Big films like Dune can push these products to their limits in unexpected ways. Avid product support apparently can dispatch live humans to your workstation same day if the software is not working as expected.
I have never heard of a support person being helicoptered in, but I wouldn’t be surprised if it has happened on a big budget production that was blocked by a software issue.
Its one of two or three editing suites used industry wide, so most likely. Also has been around the longest, iirc.
Surprisingly easy to learn the basics in a few hours, maybe try it out sometime.
