Yes. Like many here, I’ve learned to hit save A LOT. But I also want to decide when the time is right. Whether I’m writing a paper, coding, photo retouching, whatever, I flail around and experiment while working. I want to lock in my changes when I’m happy with the progress. If something goes awry I’d rather resume at the last manual save than some other weird thing I did afterwards.
I’m baffled by all the downvoting. It was also my first thought that we rarely own the software we use.
