Microsoft 'deeply sorry' for offensive tweets by AI chatbot

Microsoft has said it is "deeply sorry" for the racist and sexist Twitter messages generated by the so-called chatbot it launched this week. The company released an official apology after the artificial intelligence program went on an embarrassing tirade, likening feminism to cancer and suggesting the Holocaust did not happen.

Instead, it quickly learned to parrot a slew of anti-Semitic and other hateful invective that human Twitter users fed the program, forcing Microsoft Corp to shut it down on Thursday . Following the disastrous experiment, Microsoft initially only gave a terse statement, saying Tay was a "learning machine" and "some of its responses are inappropriate and indicative of the types of interactions some people are having with it."
