earth-moving machines don't really move earth because they are told so, machine requires fine-grained deterministic input in a certain language of motion to do what it does.

imagine if machine operator was saying "move this earth here, not not this one, 30 cantimeters to the left... yes, move this one earth here, no not here, please a bit to the right", lol

of course, someone with no exprerience with the machine would prefer telling it what to do, and he will even achieve something rough, but someone who knows what handles and pedals do would prefer the handles and pedals
