Latex already has massive amounts of libraries. Simple things like chemistry or physics typesetting for example. That's hard to just switch away from. can it do freetype fonts? I use XeLatex to change the fonts since the default gets boring. I've been doing all my math in latex for so long I feel like I can't just switch to something else.
