A robot has led human musicians during a live performance in the United Arab Emirates. The robot, called Alter 3, has a human-like face and two long arms. Video from the recent performance in the Emirate of Sharjah showed the machine turning to face orchestra members and waving its arms. Alter 3 even sang at times. The performance was an opera called “Scary Beauty,” created by Japanese composer Keiichiro Shibuya. He told Reuters news agency that the robot acted as the conductor by setting the speed and sound level of the performance. Shibuya said the involvement of robots in the everyday lives of humans is continually increasing. But, he said he thinks people will need to decide in the future how artificial intelligence, AI, can best improve the human experience. Shibuya added that he believes humans and robots can learn to work together to create beautiful art.
