Elon Musk’s brain-computer interface (BCI) startup, Neuralink, has advanced to its second human trial. During a recent Lex Fridman podcast, Musk disclosed that the second implant is operating successfully, “so far so good,” with around 400 electrodes “providing signals.”
Neuralink’s Brain-Computer Interface
Brain-computer interfaces (BCIs) are sophisticated electronic devices that enable direct communication between human brains and computers through thought alone. Although they may seem futuristic, BCIs have been a part of scientific endeavors for decades. These interfaces work by capturing the brain’s electrical activity, which a computer then interprets into specific commands, similar to how an FM radio decodes specific signals into distinct broadcasts.
BCIs can be either external or surgically implanted, as is the case with Neuralink’s device. The company’s first patient, Noland Arbaugh, who was paralyzed in a diving accident, reported significant improvements in his quality of life. Arbaugh now controls computer interfaces, plays video games, sends text messages, and browses the internet using only his thoughts.
Prospect of Superpowers
Musk ambitiously stated that Neuralink aims to grant humans extraordinary abilities beyond controlling simple computer interfaces. He envisions the technology enabling thermal vision, eagle-like vision, and even restoring sight to the blind. Additionally, Musk claims Neuralink could potentially cure several diseases and treat neurological disorders. He further posited that the implant would allow for communication at unprecedented speeds, far surpassing current methods of typing or speaking.
However, this vision remains speculative. Human communication encompasses more than just speed; it involves complex body language and expressions. Studies suggest that our brains process these non-verbal cues faster than verbal or written communication. Therefore, enhancing communication speed alone might not suffice to improve human interaction fundamentally.
Musk also hinted at the possibility of humans merging with AI through Neuralink, enhancing cognitive capabilities. While intriguing, there is currently no scientific evidence to support this idea. The concept echoes a 2019 paper on “neuralnanorobotics,” a theoretical technology that could monitor the brain’s extensive network of neurons and synapses. However, the realization of such technology could be decades or even centuries away.
