One night shift, a robot on the factory floor of German giant Volkswagen caught hold of a technician and crushed him under a moving steel sheet. This had happened on June 29 this year. Nearer home in Gurgaon, Ramji Lal, 24, was killed by a robot on a private firm's shop floor on August 12, 2015. The symbolism of the two incidents is too sharp to be overlooked. There are too many warning signals from experts about the human-created intelligent machines rapidly replacing workers in almost every field.
