Got around to listening to it out of curiosity.
It's not necessarily quad copter, but tractor based. Did not know Calif*'s mane crop was lettuce or that it produced any vegetables at all, since there hasn't been any rain since 2012. Though quad copters harvesting lettuce is a highly dubious proposition, there's certainly money to be made from tractors.
That guy was rich. Listening to him complain about the lack of PhD's to design computer vision algorithms, you thought just stop being a dick & hire people who know how to design computer vision algorithms instead of insisting they have a PhD from Berkeley. Most of the discovering, inventing, engineering, living & dying in this town is done by makers & hackers working in garages. Yet another overstuffed taco salad supported by the federal reserve.
Your other thought was agriculture might actually become a big business as our generation believed 20 years ago. Unlike what we believed, the money is not going to biologists who study genetics, but to designers of robots & businessmen.
There are no jobs for biology majors who learned about robotics on their own, only for engineers who learned about biology on their own or businessmen who can track down farmers with bucks.
It's probably a supply & demand issue. Few people can pull off the engineering side & business side while everyone can do the biology part.
A huge aversion has emerged to the genetic engineering we thought would comprise most of the expansion in food supply. A lot of that is lack of knowledge about genetic engineering & movies, but whatever. For now, you can't use genetic engineering to feed Africa. That leaves using automation to expand the biological system we already have.
