My brother wrote his master thesis in LaTex. Being a non-techie (he's an archeologist) I had to do all the 'fixing'.
We switched to LaTex after both Word and OpenOffice Writer made working with the document a non-option.
I also used git to manage changes.
This was 2009.
He could not have done it without my help with this setup. But he could also not have done it without me in Word/Writer because these apps just behave 'funny' once you reach certain complexity in your document.
Fast forward to today.
My partner is writing her PhD thesis (she's an anthropologist and hates anything that has a keyboard).
Not in LaTex but in Markdown.
It lives in a GitHub repo. She is using VSCode with some extension that translates Markdown to LaTex and then to PDF so she can have a preview (inside VSCode no less) any time.
It took me half a day to research the options, settle on that one and to set it up on her laptop (she could have never done that still though).
I spent about two hours to teach her the workflows after.
Thanks to VSCode's built-in git support she manages that also from within the app. Including branches and merges.
After the initial two hours she never needed any help from me.
I think there is a business opportunity here.
Particular people in the humanities seem to dread writing stuff for one because modern word processors are just monstrous and instable as f*ck once you reach a certain document size/complexity.
