I convince them to use TeXmacs :). At least I do not want to use LaTeX anymore (note that I've been hardcore LaTeX users for long time and also developed software to support LaTeX, e.g. TeXniscope, a previewer for DVI/PDF files in the early times of MacOS). Conversion to LaTeX format happens in the last stage of the submission (to arXiv or to a journal). It takes usually from 1 to maybe 10 min to have the file ready, maybe small tweaks for some bugs which I report and then get corrected. Three of my students wrote their PhD thesis with TeXmacs, and at least two/three other people I know. If I need to collaborate on a file which is being written in LaTeX I write my parts in TeXmacs and then I paste them in the file. Most of my presentations are also written in TeXmacs and in these days I use it to teach via Zoom, or to discuss with colleagues/students, make computations, etc... Not really using paper anymore. If you need to do algebraic manipulations, then it is more convenient to copy/paste on the screen that to rewrite the same equation several times with small variations on the paper. Using the submission requirements as an argument seems so wrong to me, it is like saying: since the final format is PDF we need to write our ideas directly in PDF... if one day editors will decide to use XML as submission format, then what? I do not want to think about mathematics with a screen divided in two parts, and the quality of the process is also very important to me. I spend maybe months to work on a paper in TeXmacs and at most only 1h in LaTeX when I really need to because editors are become used to require from the authors the work a professional typesetter would have done in the past.
