Machines have been changing farming since the industrial revolution

Inside the race to replace farmworkers with robots

Agricultural workers of the future may soon be made of steel. Can a machine pick a strawberry better, faster and cheaper than a seasonal farmworker?

I can remember when cotton was picked by hand and when hay was baled in rectangular bundles and then had to be tossed on a trailer to take to a barn.  Now hay is rolled into large cylinders and lifted with a fork onto a hay hauling rig.  I still remember farmers in rural Alabama who plowed behind a horse.  If people can design fruit pickers that are efficient is will make food more affordable and abundant and lessen the need for migrant workers.
