For the last 20+ years, I've been trying to get people to understand the point of free and open formats with pretty much zero success. For the most, they just don't care if somebody else owns all they data. Maybe if something really bad was to happen to them or a loved one as a result, they'd change their mind. Then I'd get to tell them "that's what I've been telling you for literally decades", but what would be the point?
Other than inventing time travel, I don't think there's a realistic method at this point. (and then I'm not so sure that time travel is that realistic either)
I stopped at MS Word 2.0, when the Microsoft people agreed with me that it was pretty much broken for large files, and pointed me to an FTP site where there was a new version... which also was broken. Long story short, that's when I first installed Linux and ran LaTeX and Applixware.
It really depends on what you will use it for. Using it for plain text doesn't require much, some advanced layouts require a bit more digging, if you're including fancy graphics, equations, bibliography, footnotes, etc, you're going to look at managing the relevant libraries to gandle that (they are very well made and very convenient). All in all, it can be as complex as you want, but it can also be quite easy to use.Also LaTeX is way simpler than plain TeX.
It seems that Trump will disband the time travel research group next week.
