Blind person here. I've been using LaTex for note taking since age 15. Since braille typewriters are heavy and clunky and electronic braille notetakers are expensive, I decided it was the right thing to do pretty early on. I started doing this when I transferred out of blind school. Being able to compile my notes into a PDF was definitely useful, considering I had to work with teachers who didn't have any experience with blind people before.
When I got to college, I started requesting all the materials that students normally get in LaTeX. PDFs generated with pdflatex and similar aren't screen reader accessible, but I could read the LaTeX source code just fine.
Obviously, what I write for myself isn't pure, compilable LaTeX, I usually omit the dollar signs, write things like 2^32 instead of 2^{32} etc.
By the way, the linked post was almost unreadable to screen readers, the soft dash characters inserted between every syllable made my screen reader say every syllable separately, which breaks the pronunciation rules.
