TeX people are unsung heroes to me and about as close to magic as software can get.

It's like an ancient secret order that is keeping the world safe from word-processors.

I have no idea of what they do, or how they do it, but I can't argue with the world-class results.

As with most things, it is largely a matter of practice and experience. There was a time when I was fast enough to take lecture notes in LaTeX, in courses where there were many formulas to be typeset. I did get an odd look from a professor one time, where at the end of a one-hour open-everything exam, I turned in a typeset pdf rather than handwritten answers.

Sadly, I am not as proficient with it as I used to be, as it has way too much esoterica in getting the exact layouts you want.

The biggest problem that most of the publishers still do not accept LaTeX submissions. Especially if you want to publish a book.

Hello from the world of math! Very sorry to hear about your sufferings.

That depends on the field and the specific publisher. Since the turn of the millennium some scholarly presses have stopped accepting LaTeX; this is often related to outsourcing typesetting to Indian shops that are not LaTeX-savvy.
