This obsession with "enhancing" our vision
In Sci-Fi, it looks great. Holographic screens, near-weightless glasses that do real-time augmented reality without any lag, stutter or power issues, magical interfaces that interpret exactly each and every wave of the hand or keyword spoken to it and doesn't get confused by conversations going on around or in front of it, Sci-Fi shows the awesome power of what could be. If there wasn't that pesky thing called reality, that is.
Reality means that you need a helmet on your head in order to have your eyes covered by a screen. Said helmet needs batteries, and those things are not lightweight. It mostly needs to be tethered to the workstation as well, or you won't be using it for long.
And you can get physically sick.
But the idea endures. Even when it has been killed by public apathy, like the zombie it rises again as soon as some new tech makes someone with deep pockets believe that it could be feasible.
It's the tech that just won't die, because Sci-Fi makes it look so cool.
Meanwhile, almost everyone is getting bored with Cortana.
Go figure.
