Adam Ozimek peers into the not-so-distant future. He predicts:

[Eventually you'll] have a powerful computer in your future iPhone-like-device that is connected to a special contact lens that so that screens floats in front on your face, and you steer the whole thing with your brain. The most important facts about this technology is that a) nobody will be able to tell whether you’re looking at your computer or not, and b) it will always be available to you.

Why he expects widespread adoption of this technology:

Because nobody will be able to tell whether you’re using it, genius will be indistinguishable from brain mounted computer use. If nobody uses it you will have the advantages over your coworkers that perfect memory would give you today. If everybody but you uses it you will have all the disadvantages that someone with really terrible memory has today. When everyone else uses brain mounted computers, those without them will look forgetful and unknowledgeable.

Drum argues that understanding isn't the same as information retrieval. Ozimek agrees and disagrees.
