Inside Mercedes' Silicon Valley research center

A metal typewriter sits on a pedestal churning out the next sentence of a collaborative story. For every line I typed onto paper, the AI computer controlling the hunk of metal replies with what it thinks would be a good follow up. The goal of the experiment is to see what happens when you feed an artificial intelligence only fairy tales. It's the kind of seemingly idiosyncratic thing you'd expect from IBM, Google or Apple. But I actually found it inside Mercedes Benz's R&D North American headquarters in Silicon Valley.
