Factor Substitution - Will we see robots replacing farmers anytime soon?

The answer to that question according to this NPR blog seems to be a definitive Yes! The video below shows a driver-less tractor working a field using advanced GPS systems to help with the planting. Similar technology is used to power robots that milk cows and do other farm related tasks - great as the farmer can now do something else and/or not hire a worker. Substituting labour for capital is now deemed more profitable for the business. Does this spell the end of the line for the farm hand?

“There’s very much a human element in all of the business decisions and all of the equipment selection and maintenance and fleet decisions, I don’t think you’re going to eliminate the farmer with automation.”
