That's definitely not the case in computer science and electrical engineering at least. LaTeX definitely isn't great, but I don't see a viable alternative.

Same for astronomy/astrophysics. Most of the publications are typeset in LaTeX.
Indeed, lots of people I know (mainly computer science, electrical engineering and physics) still heavily rely on it for long documents and papers.
In the 1990s I used FrameMaker. It's still around, now owned by Adobe.
There's always InDesign, but given its time to proficiency, I think the bast case for similar purposes might still be something creating LaTeX/DocBooks source that ports well to InDesign.
Can't diff a indesign file, whereas latex is easy to diff.
In my current experience with states-side academia: draw a line between the most math/theoretical departments through physics and end up at the engineering departments. The tendency to use TeX/LaTeX follows that line from a relatively high probability to zero on arrival to engineering. In European academia it stays reasonable high throughout.
