There are a lot of technologies available these days like sensors, geo-mapping, robots, and all sorts of other big data tools. The idea behind them, of course, is to make farming more efficient, and ultimately more profitable. Those technologies can also help growers farm more sustainably.

Zach and Mitchell also contemplate a world where robots take over. Skynet is becoming aware, people.
