Sorry, but an overwhelming amount of people commenting in here are extremely ignorant of the modern agri-food system.
The notion that robots and drones will eliminate monocultures and chemical inputs is wildly untrue. In some minor cases they will reduce the need.
It amazes me that software engineers think they have the panacea for whatever faults they see in our food system without a full understanding and history of it.
That's false. Homogeneity makes it easier to harvest, process, and store crops. It also drives perfect competition which brings cost down on the commodity market.
We're not moving away from nitrogen fertilizers. Ever. Why?
Look at the following three graphs: global population, staple crop yield, and nitrogen fertilizer application.
Now overlay them. That's why.
Also, there are myriad chemical inputs that cannot be removed simply due to free labor. Sure, a robot can pluck weeds, but what about fungal and bacterial diseases?
