In one experiment, a doctoral student and a robot independently answered a set of questions through a computer, and a group of scientists went to identify which answers on the computer screen were made by doctoral student and which answers were made by robot  The error rate of identification results is as high as 78%
Some people think that the set of questions raised in the experiment must be inadequate, since they can't get a group of scientists to tell which are from doctoral student and which are from the robot
That robot is the latest generation of IBM products
