Author here! I'd like to take a second to point out that the audience I had in mind when writing this article was mostly my fellow classmates in college. In school we were hastily introduced to LaTeX freshman year and were required to typeset our homeworks before submission.
The point of the article isn't "you should never use LaTeX" but rather "hey, there's this other, simpler tool that you might like better!" plus some starter templates to make the transition easier.
Importantly, I encourage everyone to use the tools that they feel most comfortable using!
I'd also add that while Markdown and LaTeX can do some of the same things, they're designed toward very different tasks. I've used both numerous times in my career, and I can't remember a case where it's been ambiguous which tool was more appropriate for the task.
If it's going to be printed, you probably want LaTeX. If it's going to be rendered to a screen, you probably want Markdown. If it's going to be rendered to a screen and have math in it, you probably want Markdown with some LaTeX for the math. If it's going to be rendered to a screen and printed, better start looking for a job, because that project is going down in flames.

>Jeremy here. Here to answer any questions or comments that you have. > >But more importantly - I need to mention that Terence Parr did nearly all the work on this. He shared my passion for making something that anyone could read on any device to such an extent that he ended up creating a new tool for generating fast, mobile-friendly math-heavy texts: https://github.com/parrt/bookish . (We tried Katex, Mathjax, and pretty much everything else but nothing rendered everything properly). > >I've never found anything that introduces the necessary matrix calculus for deep learning clearly, correctly, and accessibly - so I'm happy that this now exists.
