@tomas Even now, actually, it seems to be mostly appreciated by maths and sciences people. Example: linguistics is in the same school as philosophy and psychology here, and there's a balance of historical linguists and more psychology/biology-based linguists (language processing, phonology/phonetics, etc.).
There seems to be a comparable balance of people who know/don't know how to use LaTeX.
One shocking exception is my phonology professor who works with oral cavity ultrasounds to study pronunciation and who still hasn't picked up LaTeX, or, IIRC, any sort of automation. His workflow must be torturous.
