I too love LaTeX but it's important to remember that the writing experience might be nice and elegant in LaTeX with the right stys and ShareLatex and whatnot, but the editing experience is decidedly not. Everyone who has used it in any serious form with page limits knows the stress of slowly varying their figure sizes and hoping it will squish into the limits.

Very honestly, part of the reason I don't bother with any new "LaTeX reimagined" projects is because either (a) they are written by LaTeX nonbelievers who don't understand the complexity of beautiful typesetting, or (b) I don't want to learn another markup+ language or mental model. The latter is increasingly annoying to me.

Out of curiosity, is LaTeX compilation benchmarked on the M1 processors? Is it better? Has anyone experimented with magic Raph Levien-style SIMD magic (a la stack monoid) compilation for LaTeX? I just want LaTeX but really really fast.
