The rise of the robo-restaurant: AI is ready to take your order

KFC is using facial recognition and AI in China. A large interactive screen greets customers with an image of themselves, taken from in-built cameras. After guiding them through the order process, and entertaining them along the way, the AI has learned two things: what they look like and what they like to eat. It lets people pay using facial recognition too, and the next time they visit it will not only recognize them, it will remind them of their last order.
