AKA what CS PhD students have been doing ~forever. I guess this is like medical researchers "discovering" basic calculus or an office worker discovering that SFTP, sshfs, and git work fine and they don't need Dropbox after all. What's common knowledge in one field can apparently still be alien to people outside the field, even in the age of LLMs. Just wait until the author finds out about Overleaf...
Or what every researcher has been doing for literally decades (except with other versioning systems, but still typesetting without Word or Adobe).
No need for techbros to pat themselves on the back as innovators.
I typeset my novels in LaTeX and use GIT. I even just clone a base repo whenever I'm going to release another.
