“For example, the way business mail used to work was that the bureaucrat in question would record their message onto a tape, and then send that tape off to a special department full of typists to actually turn that voice recording into a letter. That whole concept is not only gone, but it's such a foreign idea that it sounds like something you'd write for a dieselpunk novel. The moment we started putting computers on people's desks, we expected everyone to know how to type.”
It’s true that executives now do their own typing, but that is not automation. It’s actually a rare case of modern work becoming less specialized, with a whole category of highly specialized workers (typists) ceasing to exist.
If the executive uses voice-to-text technology, then that would be a case of automation.
