The End of Migrant Workers
The writing is on the wall. In a fairly short time as such things go, migrant workers (and for that matter, domestic farm workers) will become an anachronism. Writing algorithms for farm machinery is much simpler than writing them for automobiles. There are far fewer variables involved, and the "obstacle course" is much easier to navigate.
Robots Take the Wheel as Autonomous Farm Machines Hit Fields
Robots are taking over farms faster than anyone saw coming.
The first fully autonomous farm equipment is becoming commercially available, which means machines will be able to completely take over a multitude of tasks. Tractors will drive with no farmer in the cab, and specialized equipment will be able to spray, plant, plow and weed cropland. And it’s all happening well before many analysts had predicted thanks to small startups in Canada and Australia.
... [Regarding weed control] “The savings on chemicals is huge, but there’s also savings for the environment from using less chemicals and you’re also getting a better result in the end,” said Bradford, who’s run the farm for about 10 years. Surrounding rivers run out to the Great Barrier Reef off Australia’s eastern cost, making the farm particularly sensitive over its use of chemicals, he said.

Cheaper. Better for the environment. The only remaining question is why the U.S. is trailing behind Canada and Australia in developing and selling this equipment as well as hiring American workers to build the advanced machinery. It's almost like we don't want to be the world's technology leader.
