Artificial Intelligence: Tay AI chatbot has been terminated after 16 hours of activity
The Tay AI bot has been released on 23 March 2016 by Microsoft Corp. to be used for the Twitther platform. It was taken off-line after about 16 houres of being used. The reason was Tay had learnt from users to response in very inflammatory way. BTW here is link to Sophia the robot, also with some problems: https://www.youtube.com/watch?v=W0_DPi0PmF0
IMO it's another proof that most of contemporary bots are far from intelligence and work mostly "mechanically", taking into account more syntax, lexical aspects with shallow knowledge than their semantics.
