Yes, eventually you’ll have the implant, and those brain chips may arrive in two waves: initially for the treatment of chronic illness and then for performance enhancement. Because of the military’s interest in the latter, however, those waves might come crashing down together. From “The Future of Brain Implants,” an article by Gary Marcus and Christof Koch in the Wall Street Journal:

“Many people will resist the first generation of elective implants. There will be failures and, as with many advances in medicine, there will be deaths. But anybody who thinks that the products won’t sell is naive. Even now, some parents are willing to let their children take Adderall before a big exam. The chance to make a ‘superchild’ (or at least one guaranteed to stay calm and attentive for hours on end during a big exam) will be too tempting for many.

Even if parents don’t invest in brain implants, the military will. A continuing program at Darpa, a Pentagon agency that invests in cutting-edge technology, is already supporting work on brain implants that improve memory to help soldiers injured in war. Who could blame a general for wanting a soldier with hypernormal focus, a perfect memory for maps and no need to sleep for days on end? (Of course, spies might well also try to eavesdrop on such a soldier’s brain, and hackers might want to hijack it. Security will be paramount, encryption de rigueur.)

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.”
