Since we’re not typists, of course the speed of text input is not the bottleneck, but thinking, getting motivated, etc.
But that’s not what Vim is (only) about. Editing text with Vim a pleasurable experience unlike any other. See the parent’s comment on that as well.
It is, however, the steepest wall I’ve had to climb usability wise. Probably akin to Blender, where everything is different from what you would expect at first, but, hopefully, for a good reason.
