The point where something is unfixable in LaTeX is much more complex than the point something is unfixable in Word, where I seem to jump down the rabbit hole on relatively simple documents.
That is a matter of opinion. I think the lack of source code is a problem of incredible complexity, in that overcoming that hurdle would require one to somehow force MS to fix something.
I think LaTeX starts marginally easy, gets complex and fiddly but then pretty much just stays at the same level of complex and fiddly. Word starts very easy, gets complicated quickly and eventually presents un-fixable problems, no matter what your skill level.
