1-There is a demand for writing scientific papers. Because LaTeX's mathematical typesetting can be said to be the best (no one), the formula is beautiful and easy to write. At the same time, if you want to contribute to the journal, some will provide you with LaTeX templates. You can only learn to use latex.

2- those with publishing needs. Of course, this can also be classified as 1. I mean, you want to typeset a novel and a collection of poems, and then print and bind them yourself … then you can learn LaTeX. I'm sure they will be very happy if you send the documents typeset with LaTeX to the printer.

3- I heard that someone used LaTeX to organize electronic notes. For example, advanced mathematics class, college physics class ... Of course, if your typing speed is fast enough, you can follow the teacher to type on the keyboard in class. But the input speed of the formula ... I believe it is not as fast as handwriting. But it's good to organize your notes.

4- lovers. There is no reason for this-latex is such an excellent, easy-to-use and free tool that learning it is a pleasure.

5- People who don't want to spend money on a suite like Microsoft Office. Although there is OpenOffice, LaTeX is another style choice.
