As robots become more social, humans will encounter more and more robots in the service industry, said Illah Nourbakhsh, a professor of robotics at Carnegie Mellon University and author of Robot Futures.
At first, humans will increasingly encounter robots more via telecommunications and it will become harder for them to distinguish robots from humans. And eventually, robots will begin to replace more service jobs-like waiting tables.
There are already novelty robots in some places, including Japan where robots act as servers, taking and delivering orders.
However, unlike a human waiter, a robot server will have all kinds of information about you before you even tell it what you want. Because robots will be connected to the Internet, they will be able to access all of the information that is available about you online to predict what you may like to order.
