As far as I can tell, the legal world still runs completely on Word redlining/track changes. Also, Excel almost literally runs many businesses.

As long as those are true, I'm not sure you can say "there just isn't much you really need eg. Word for", unless you're never on the business side. If you deal with the people who use them, you probably also want to use them to avoid headaches. Network effects are a bitch.

If you're only ever slinging code, sure, congrats, you may never need to use either.

Note, I'm not arguing that either is good.
