Woz describing the thinking of the 1970s: We thought computers were going to be used for all these weird things--strange geeky things like controlling the lights in your house--and that turned out not to be the case.

An early generation of enhancement implants might help elite golfers improve their swing by automating their mental practice. A later generation might allow weekend golfers to skip practice altogether. Once neuroscientists figure out how to reverse-engineer the end results of practice, "neurocompilers" might be able to install the results of a year's worth of training directly into the brain, all in one go.
That won't happen in the next decade or maybe even in the one after that. But before the end of the century, our computer keyboards and trackpads will seem like a joke; even Google Glass 3.0 will seem primitive. Why would you project information onto your eyes (partly occluding your view) when you could write information into your brain so your mind can directly interpret it? Why should a computer wait for you to say or type what you mean rather than anticipating your needs before you can even articulate them?
By the end of this century, and quite possibly much sooner, every input device that has ever been sold will be obsolete. Forget the "heads-up" displays that the high-end car manufactures are about to roll out, allowing drivers to see data without looking away from the road. By the end of the century, many of us will be wired directly into the cloud, from brain to toe.
