Nice story on the application of technology to one of the oldest, and most important forms of work - rice farming. The use of drones reduces pesticide use by more accurately and evenly distributing the it. Anytime you can increase agricultural yield by using less pesticide is an unambiguously good thing. Also note the rise of new jobs for farmers as drone pilots, as well as the rise of an economy servicing and refuelling the machines, some evidence of the techno-optimist case.
