NYU Stern professor Amy Webb gave her annual Emerging Tech Trends this week at the South by Southwest conference. (Hat tip to Dan Churchwell for the mendation.) She highlighted a number of trends from food grown in warehouses and 4D printing to genome editing. After reviewing some of the tech trends she proposed three possible es: optimistic, neutral, and catastrophic. The talk is worth watching.

You can also hear an EconTalk interview she did with Russ Roberts on her new book, The Big Nine: How The Tech Titans and their Thinking Machines Could Warp Humanity. The Big Nine addresses the challenge that most of the development and implementation of artificial intelligence is done by nine corporations who Webb worries are building AI systems that will be negative for society and humanity.
