There is always proofreading and editors involved for grammar and style anyway. Some authors also keep a typist /editor formally or sometimes informally :friends/family /spouse .
However all that apart typing without backspace is very different. Try it sometime , you have think ahead a bit form your sentence /block fully , it is harder , I think it will always be slower but maybe for someone used to that it is different.
Yep. Grew up in an era when mechanical typewriters were the standard "tech" of the day for writing. And yep, it's far more difficult. Finger strength, key jamming, and the regular use of white out fluid, or pen ink markup to correct first drafts. Listening for the margin warning bell and deciding on the fly if you should reach for the carriage return lever or push your luck. Centering titles by counting the letters, dividing by two and adjusting the carriage to suit. Oh yeah. Funsies. Don't miss those days. In speed tests for clerical positions, e.g. secretary in a law office, etc, backspacing to fix something meant the loss of a word in your speed rating.
