This picture taken on December 21, 2023 shows Kiwa Usami (C), who has cerebral palsy and performs with one index finger, playing an AI-powered piano during a Christmas concert rehearsal of Beethoven’s Symphony No 9 with the Yokohama Sinfonietta orchestra in Tokyo. To assist players, the Anybody's Piano augments a performance by adding whatever keys are needed but not pressed. (Photo by Kazuhiro NOGI / AFP)
