IBM computer struggles in Cambridge debate on the dangers of AI

AI has the potential to power driverless cars and smart cities. But critics say the technology could perpetuate bias, put people out of work and even threaten human existence. About 500 university students attended Thursday's debate, hinting at just how controversial the technology is. The IBM machine, which was defeated by a human in a one-on-one debate nine months ago, delivered each team's 4-minute opening speech using submissions sourced ahead of time from over 1,000 people. The rebuttals by each side were done by the human debaters, who also delivered the closing arguments.
