If you try using a vintage typewriter you will reconsider. It was a ton more work than now.
(1) Typewriter keyboards were actually physically strenuous... find an old manual typewriter and type a couple pages on it and see how whether you feel like typing a dozen more. This was rectified beginning in the 60s I think, but manual models were still around for a while due to cost.
(2) Even once electric typewriters were invented, dealing with minor typos, let alone more major textual surgery, remained a huge hassle until the personal computer / full word processor came about allowing on screen editing... Just imagine typing most of a page only to realize you forgot a sentence near the middle, or even made just a small typo. which is around when typists stopped being a thing, because then, and only then, typing had become so automated that a reasonably skilled bureaucrat wasn't really saving much time (and losing latency) by using the typing pool, especially for brief, urgent memoranda.
It is a case of automation working so well, you don't even notice it at all and thus think nothing was automated, until you think about it in more detail.
The automation with a word processor is not the input (the typing), it's the page layout and reflow, and being able to edit and get WYSIWYG before committing to the printed page.
My best typing experience, typewriters manual or electric, or computer keyboards, was the IBM Selectric. Second best was on an AT&T 3270 (!?!) with a mechanical clicking keyboard, similar to original IBM PC, but even better. I mean using a 3270 isn't great fun but the typing was great.
