Hundreds of thousands of people
around the world already have brain-computer interfaces, which scientists have
been developing since at least the 1970s, in part thanks to funding from Darpa.
Some experts predict that number will reach one million in the next decade as
the science becomes more sophisticated. But the inner-workings of our brains
are still not well understood, and the real returns on this kind of neuro-technology
are just beginning to emerge.
The promise of brain-computer
interfaces is to give sight back to the blind, restore sound to the deaf, and
provide a sense of control to our bodies. However, some believe that neuro-technology
will soon give us all superpowers. Neuralink aims to improve human cognition,
to compete with the likes of AI. Zuckerberg's idea is more focused on a
mind-reading machine. Kernel, is working on creating a brain interface that
develops real world applications of high resolution brain activity.
