Over a year later, Musk’s Neuralink still 6 months from human trials

On Wednesday night, Elon Musk hosted an update from his brain-computer interface company, Neuralink. Most of the update involved various researchers at the company providing overviews of the specific areas of technology development they were working on. But there wasn’t anything dramatically new in the tech compared to last year’s update, and it was difficult to piece the presentations together into a coherent picture of what the company plans to do with its hardware.

But probably the most striking thing is that last year’s update indicated that Neuralink was getting close to human testing. Over a year later, those tests remain about six months out, according to Musk.

Lots of tech

Neuralink involves a large series of overlapping technical efforts. The interface itself requires electrodes implanted into the brain. To connect those electrodes with the outside world, Neuralink is using a small bit of hardware implanted in the skull. This contains a battery that can be recharged wirelessly, and a low-power chip that gathers data from the electrodes, performs some simple processing on it, and then transmits that data wirelessly.
