An experiment with artificial intelligence at the annual Richard Wagner festival in the German town of Bayreuth has drawn boos from the audience after producing a staging that appeared to leave some spectators confused. Curator Marcus Lobbes and his team were greeted with boos and whistles as they took to the stage at the end of Saturday evening’s performance of “Götterdämmerung.” The German news agency dpa reported there was warm applause for the singers and musicians, and particularly for conductor Christian Thielemann. Festival organizers had said ahead of the performance that it would be the first time AI took part on stage at the event.
