    We’ve had this technology for decades, Disney even had something planned around it so you could sit around and have your phone magically charge, for Disney specifically the problem was that it would build up dangerous amounts of electricity making normal objects deadly but more broadly the problem is that it is ungodly inefficient, like I’m talking exponentially inefficient, electricity follows the square cubed law, meaning for every one unit you move away from the source you loose 3/4 of your original energy.

      I mean, a wireless keyboard only has to send so little data and uses so little power (if not backlit) that even RFID is viable for it unless you need to move it a lot.

      Also, connecting PC peripherals wirelessly was the original idea for Bluetooth in 1996, although that drew too much power from their batteries to be really viable before BLE.
