“Cables are disappearing. Communication between components, such as pointing devices, microphones, displays, printers, and the occasional keyboard, uses short-distance wireless technology. [By 2009.]”

Ray KurzweilThought Leader

Inventor, futurist and author of The Age of Spiritual Machines

By 2009 Wi-Fi networking and Bluetooth mice, keyboards and headsets were common, but displays, printers, speakers, charging and most peripheral connections remained wired (USB/HDMI), so cables had not 'disappeared'. Kurzweil scored this correct; critics including IEEE Spectrum disputed that reading.
