Software is eating the food world

Silicon Valley has become obsessed with "disrupting" food. Alarming headlines grab the public's attention -- stories about meat grown in labs, flavorless "Soylent" meal replacements and "chickenless eggs." The tech industry is "disrupting" food by replacing the real with the fake. But other parts of the industry are doing the opposite: replacing the fake with the real. The newest Silicon Valley food revolution isn't about bio-engineering strange new food replacements, but using algorithms and artificial intelligence (A.I.) to transform how real food is marketed and distributed.
