Elon Musk's Neuralink has FDA approval to put chips in humans' brains. Here's what's next.

Elon Musk's SpaceX recently launched the biggest and most powerful rocket into flight, even though it did make it into orbit. But the world's richest man isn't content on expanding his sci-fi inspired technology into just the cosmos. Neuralink, the tech startup co-founded by Musk, also wants to embark on a fantastic voyage into the brain. Two weeks ago, the company announced it had gained approval from the Food and Drug Administration to begin trials to implant brain chips into humans. We don't know when trials will begin, but there's plenty of buzz around Neuralink's development of a brain-computer interface.
