Except that it will not be an implant because individual neurons in the brain have an irritatingly low bandwidth of only a few bits per sec.

Instead it is much cheaper and hassle-free to use the firehose connection that already exists into the brain: the eyes, for which even protocols for communication are established. Screens in contact lenses are my bet on where the future of computers are headed. That will with time largely remove the need for physical objects that transfer information.

The interesting part is how Apple in 2020 will spin that they ten years earlier named a display far to bulky to fit into your eye "Retina display".
