In many cases, robotic manufacturing is more efficient than employing human workers. It is also safer, being less likely to lead to human injuries. There are, however, certain circumstances in which humans are superior to robots.
First, humans are far more versatile than robots. A robot designed to do spot-welding is only capable of welding; it cannot suddenly learn to deliver packages or cook meals or answer the telephone.
Next, in many areas of the world, people are less expensive than robots.
Robots cannot handle unforeseen circumstances.
Another issue with robots is that they lack creativity. Although a machine can manufacture, for example, a rug much faster than can a human, the great artistry of medieval tapestries depends on the single artist. When we move into mass production by robots, we lose that quality of individual workmanship.
