Aside from your arrogant tone, there is a gaping flaw in your logic.
Buy a good video camera and see your AF problems melt away?
Mirrorless cameras with good AF already exist.
BTW, I said AF is sometimes indispensable, I never claimed it should supplant MF. If you don't have someone pulling focus, for example. In the following clip, from 1:08 - 1:11, where the camera moves quickly from the barber to the customer, is a case in point.
Wait, I forgot to add boldface type, exclamation marks and references to how pros have been doing things for decades, as if the industry is standing still.
