From HAL to Wiimotes and Kinect, musicians have predicted the future of machine/human interaction. Because music connects with time, body, and emotion in a unique way, they test the limits of technology. Now it's time to work out what comes next. What's going on here - how did musicians manage to invent major digital interaction tech before anyone else? Before the iPad, the first commercial multi-touch product was built for musicians and DJs. Before the Wii remote, musicians built gestural controllers, dating back to the early part of the 20th century. Before the moon landing, Max Mathews' team of researchers taught computers to make music and sing, inspired HAL in 2001: A Space Odyssey, and may have even built the precursor to object-oriented programming.Music's demands - to be expressive, real-time, and play with others - can test the limitations of technology in a way people feel deeply, and help us get beyond those limitations.
