Who needs humans? At a ramen noodle shop in Nagoya, Japan, a pair of robotic arms serve up 80 bowls of noodles a day to their hungry customers. They never get tired and they don't need tips.
Of course, one could argue that there's no art in a robot making food. But with some types of food, no art is needed. You think people at McDonalds are putting their own unique spin on burgers? No. Which is why, eventually, robots will be doing all the work at fast food restaurants. Because a robot never spit in a burger.
