A first-generation commercial brain-computer interface (BCI) is being released by Emotiv Systems later this year. What does the future hold for BCI?

By 2050, and likely sooner, you will be able to buy a BCI device that records all your dreams in their entirety. This will be done in one of two ways. One method would be to use distributed nanobots less than a micrometer in diameter to spread throughout the brain and monitor the activation patterns of neurons. By this point, cognitive science will have advanced enough to know which neural activation patterns correspond to which sensory experiences. This has already been done with cats (using electrodes, not nanobots), where researchers led by scientist Garrett Stanley were able to extrapolate what a cat was seeing merely by monitoring the neurons of its visual cortex.

Scientists at the Boston Retinal Implant Project recently developed an implant that will help those with degenerative blindness see again.Although not a complete bionic eye, this implant is a huge step forward in that direction. It works by being implanted at the back of the eyeball and transmitting light to the brain via a tiny nerve.

Machines will achieve human-level artificial intelligence by 2029, a leading US inventor has predicted.

Humanity is on the brink of advances that will see tiny robots implanted in people’s brains to make them more intelligent, said Ray Kurzweil.

The engineer believes machines and humans will eventually merge through devices implanted in the body to boost intelligence and health.

“It’s really part of our civilisation,” Mr Kurzweil explained.
