There will come a day when most humans don't just use technology, or wear it on their heads and wrists, they inject it into their bodies to improve themselves.
That's the vision of both sci-fi writers and people who call themselves "futurists." One of them, Ray Kurzweil, even has a name for it: the singularity. That's a point when technology and our bodies merge and we bcome different creatures at the next level of evolution.
There are a few brave souls at the edge of the singularity now. Sometimes they even call themselves cyborgs. These are people who have implanted tech directly into their bodies, for a variety of reasons.
Neil Harbisson had an antenna implanted in his head
Neil Harbisson is probably the most famous cyborg. He was born with a severe form of color blindness that doesn't allow him to see color at all.
In 2004, he, along with Adam Montandon, developed a device he calls the "Eyeborg." It translates colors into sounds, musical notes, piped into his brain. It allows him to experience color that way.
Here's another look at Harbisson's antennas
In 2010, Harbisson cofounded the Cyborg Foundation that supports other people who either need or want a tech implant.
A documentary about Harbisson won a film award
Harbisson became the face of this cyborg movement in 2013, when the film "Cyborg Foundation" won a $100,000 grand prize from the GE/Focus Forward Filmmaker Competition.
