How Hillary Clinton and Donald Trump lack tech savvy

Rachel Law, the 20-something co-founder of a New York startup called Kip, is sitting next to me at a café, tapping her phone screen to show how the company's service based on artificial intelligence allows users to shop while on Slack by communicating not in typed or spoken words but in cartoonish emoji. If Law were doing this demo for either Donald Trump or Hillary Clinton and used the terms artificial intelligence, Slack and emoji in the same sentence, each candidate's brain would no doubt seize up like an engine that had run out of oil. We have a problem, folks. Over the next four-year presidential term, a swarm of fantastic new technologies, such as artificial intelligence, virtual reality, blockchain, personal genomics and drones, will profoundly alter society, business and geopolitics in ways we've never seen. And our two major-party presidential candidates don't have a clue.
