We’ve prioritized “intuitive” over “efficient.”
I would argue, overall, it’s more efficient to aim for the former than the latter, especially if we are talking about the wide range of people who need to use a computer.
But I’m curious as to the “actions per minute” type of efficiency that people are talking about here. I’m an engineer, who has moved into computer programming. I would say the bottleneck for me is never that I have to move my hand to my mouse, but it’s always about thinking and planning. I feel like this “it’s so much more efficient” is viewing us as almost machines that are just trying to output actions, rather than think through and solve problems.
The net result was a populace that didn’t need support as much, because they were used to reading the docs. If a component died, the docs would tell you how to diagnose and fix it.
I think this is more of a problem that it went from an extremely niche thing, to something that almost everyone is required to use, rather than a move away from keyboard only. Or, maybe, the rise of the mouse opened the computer to everyone being able to use it, which is why it has become so ubiquitous.
Now I see your original point in a new light. I just viewed it as a natural progression that the mouse would take over as the primary input because of it’s useful and intuitiveness. So when you say you “hated” this, I interpreted as a hate for mice in general and the wishing for pre-mice days. Rather than just a move back towards the keyboard being the primary interface.
