Kimbal Musk, co-founder of farm-to-table restaurant group the Kitchen, board member at Chipotle, Tesla, and SpaceX, and younger brother to Elon, thinks hydroponic vertical farming—that is, soil-less, indoor, LED-lit agriculture—is the future of food.

Dan Barber, renowned chef, restaurant owner, author of bestseller The Third Plate, and crop rotation evangelist, strongly disagrees.
