Why do CS doctoral candidates have such a fascination with typesetting? I mean, be into whatever you’re into, I guess. But as soon as someone starts talking about LaTEX and how they spent months on their macros, I think “another hapless victim has fallen into LaTEX’s trap.” It’s like an ant lion that feeds on procrastinating students.
Why does anyone care about typesetting? Probably because they spend a lot of time working with text and have therefore developed a level of taste.
Just because the bottom 80% of consumers have zero taste and will accept any slop you give them doesn't mean there isn't value in doing something only appreciated by the top 20%. In any field, not just typesetting. Most people have ~no refined endogenous preferences for food, art, music, etc.
