Latex lets you write equations quickly. Whether that makes it worthwhile to learn depends on how many equations you write and how quickly you want to be able to change them.

I also like being able to write my papers in vscode, with all the shortcuts and vim settings that I’ve gotten used to from coding. If Vim is second nature to you, it’s frustrating to have to switch over to ms word. Vscode has a good latex plugin.

That said, it did take some getting used to. Anything hard and potentially useful can become a “fetish” whereby we fool ourselves it’s the usefulness that motivates us but really it’s the hardness. I recall a time when I tried to use matplotlib to format all my plots, with labels and such. Horrible experience but I was really proud of these ugly graphs I’d make entirely from code. Then one day i just started saving them and opening them in illustrator for all the bells and whistles. Haven’t looked back.
