Brain-Hacking Tech Gets Real: 5 Companies Leading the Charge

Tesla and SpaceX CEO
Elon Musk made waves in March when he announced his latest venture, Neuralink, which will design so-called brain-computer interfaces (BCIs). Initially, the BCIs will be used for medical research, but the ultimate goal is to prevent humans from becoming obsolete, by enabling people to merge with artificial intelligence.
While these may seem like lofty goals, Musk is not the only one who's trying to bring humans closer to machines. Here are five companies that have doubled down on hacking the brain.

• Neuralink
• Facebook
• Kernel
• Emotiv
