     Back in the 1970s, the robots were coming for our boring manufacturing (生产) jobs.Now, they're

coming for our boring table service jobs.Korean company ITM Technology has developed the restaurant

concept around a little robot that fulfills the role of a waiter.Robo Caf? avoids ordering errors, reduces

staffing costs greatly for restaurant owners, and even brings the boss all the tips.

     Japan is preparing for some very tough times ahead.When its aging population become too old to

work, labor is going to be in severe shortage.So inventive technology departments are exploding with really fascinating ideas to take the pressure off when it hits.

     To small caf? and restaurant owners, the solution might well look something like Robo Café, a

restaurant designed to operate as efficiently as possible with the absolute minimum human workforce

possible.The building needs to be designed with small horizontal (水平的) pathways leading from the kitchen to all the tables.A small team of waiter robots can then get around to every table in the house when they're asked to come.Customers can either order orally, or touch a screen on the robot's belly.When the

kitchen has finished preparing the food, the robot brings it out to customers.

     Dan Carlin talks about the "kitchen of the future ", where everything is automated and the labor is free

because you own it.Really, the_kitchen_of_the_future_is actually_the_kitchen of_the_past, when you

consider that throughout human history, there have been many examples of slaves working for no pay.

     As Carlin points out, today's concept of slavery is mostly restricted to nonhumans.And the ownership

of robot labor in a Robo Caf ?type situation will almost certainly prove itself far more economical and

dependable than a human workforce once the technology itself becomes mature.Of course, slaves have a worrying habit of rising up against their owners.
