The point was that there are all kinds of all-field applications that do not require the big behemoth tractor, but the current farmer still drives the big monster tractor when a robot with wheels not much bigger than fat bike tires can do a lot of the weeding, seeding, and inspection and trimming and whatever ALl without needing an air conditioned cab and driver....
