It's the people who made the robot that are bright. The people who use the robot may or may not be bright...all you can say for sure about them is that they had enough money to buy a robot.

As robots get more and more autonomous, and so are able to take over more jobs and need less human supervision, you reach a point where the owner of the robot is not really contributing any more to society than the people the robots have unemployed.

This will be especially true a generation later when the owners who actually bought the robots are gone and the new owners inherited the robots. The danger there is that we end up with a society where the the robot owners are like medieval lords, the robots are the serfs, and the rest of humanity are beggars, and your place in the world is largely fixed at birth except for a lucky few who are able to marry into the robot owner class.
