I was at your position until I started using them and I found it more pleasant that MS Office. Of course for personal use not business as it is not as capable of advanced features.
Apple with pages are exactly where they want to be. A free app that makes Apple users not pay for Office license. Its more than enough for personal use. They do not aim to go head-to-head with Office in the business environment. Apple was never a business machine.
I will have to look into that. Last time I fiddled with the GUI , it bugged real bad.
This is scary given that near all governments and business use Office. How they have managed the corruption? I never recall getting any word processor document corrupted. I am actually more wary of LibreOffice since its FOSS and "volunteer" maintained.
What does Scrivener do for long writing that MS or Libre can not do ?
A quick look up says MS Word will struggle after 400 pages. I thought most/many books are written in docx. I guess maybe they write them in separate files.
Working backwards I can say yes about books. At least the last one I worked on. Each chapter was a seperate file. Sure Word (etc) have special features like Master Documents but seperate files was simple and worked fine. I am sure there are technical upsides to master documents and such but the complexity isn't worth it. Author time on a book is typically researching and writing and rewriting and such not formatting and making global updates.
Also the publisher will take care of final assembly and layout, etc. Page sizes are different, high-quality figures are coming from elsewhere, they have their own color limitations, and they may have some plan for connecting online and offline. Ideally let them deal with it.
Then I suspect priorities and therefore formats differ across domains. A master document with global find and replace may be more important if you're working on the next SQL standard. I would guess math people still write in LaTeX -- or at the least that's a format a math book publisher has to accept. And of course we're completely ignoring fiction, etc.
As far as corruption goes, I'd say that varies by tool. I haven't had corruption issues with Word within it's <400 page target market but it does get stuck in local squirley formats. Where it starts doing something based on some weird hidden code from some copy/paste that that you can't see because we're not supposed to think about formatting like old WordPerfect's reveal codes but yet it's still there. WordPerfect's Reveal Codes was messy but at least you could fix the mess if you knew what you were doing.
Speaking of which, I find copy/paste that preserves all formatting ridiculous as a default. If you're working across a combination of sources, authors, etc, the probability that everyone used the same typeface, etc is low. I am not sure who decided that copy/pasting across documents should result in something that looks like a ransom note by default.
Then Excel has historically corrupted itself with more complex formulas across more data increasing the probability. Maybe that's better in the 2019+ versions but it's really not the right tool/design for big data. Sure it's been able to go up to 1M rows since 2007 (and even more with the Power add-ins) but I find it best when you stick to its original 32K limits. In lives past I actually had to edit the underlying XML with a text editor to fix stuff.
Similarly, some years ago I worked with one major valuation firm that had a policy that every new engagement started with a blank sheet -- analysts couldn't use previous models or templates less any corruption spread like a prion. Then their goal was to finish the engagement before the Excel model got too corrupted. vF and archive and hope you never have to look at it again. It doesn't help that Excel's copy/paste between documents can bring over extra junk like named variables and linked formulas.
Regardless these are the standard tools of corporations/businesses. Everyone's got them and everyone knows that everyone has got them. In a collaborative environment you can't just say I don't like the tool everyone else is using and do something in an incompatible tool. And otherwise when you trade documents you want bug-for-bug compatability with what everyone else is using. It's not acceptable to fix conversion errors with every back and forth of a file.
Things change though. Tableau (PowerBI, etc) has been displacing Excel for some years (obviously starting first where it is weakest which has been big data). Then there are bigger organizational shifts where instead of a finance person doing a simple model in Excel, much more sophisticated predictive analytics are undertaken by a data science team working in Python from data already centralized in a database, etc.
On the low-end of the market I see students and recent graduates who never used MS Office -- they've been using Google Docs their entire academic career. If they join a startup or similar right out of college that might continue.
What I don't see is something like Pages taking over for the simple reason is that it is a) not cross-platform and the one platform it is on is not Windows. It may be great -- objectively and singularly best at what it does -- but the vast majority of businesses are not switching 100% to Mac any time soon so they will only consider software that runs on Windows and ideally across Mac, Windows, and Linux. Pages, etc doesn't offer that and no sign that will ever happen.
My predictions for the future of this kind of software is:
-MS remains the standard for the short-term
-Low-cost options like Google Docs grab increasing share of the low-end (while expanding the definition of the low-end)
-In the long-run, the traditional word processor/spreadsheet/presentation paradigm (and as such these suites) become obsolete in the context of entirely new ways of working and communicating
