In this Wednesday, Jan. 10, 2018, photo, musician Stevie Wonder plays a so-called "smart" piano, an internet-connected device designed to teach people how to play, while piano teacher Gabie Perry stands next to him at The One Music Group’s CES booth in Las Vegas. Wonder spent about 15 minutes playing tunes as a crowd gathered at the booth. Wonder says he likes to visit the conference to see new things and meet people. (AP Photo/Matt O'Brien)
