After weeks of anticipation, details on Elon Musk’s brain-computer interface company Neuralink have finally been revealed. In a detailed report on the website Wait But Why, Tim Urban recounts insights gleaned from his weeks meeting with Musk and his Neuralink team at their San Francisco headquarters. He offers an incredibly detailed and informative overview of both Musk’s latest venture and its place in humanity’s evolution, but for those of you interested in just the big picture, here’s what you really need to know about Neuralink.
Right now, you have two primary “layers” to your brain: the limbic system, which controls things like your emotions, long-term memory, and behavior; and the cortex, which handles your complex thoughts, reasoning, and long-term planning. Musk wants his brain interface to be a third layer that will complement the other two. The weirdest thing about that goal may be that he thinks we actually already have this third layer — we just don’t have the best interface for it:
We already have a digital tertiary layer in a sense, in that you have your computer or your phone or your applications…The thing that people, I think, don’t appreciate right now is that they are already a cyborg…If you leave your phone behind, it’s like missing limb syndrome. I think people—they’re already kind of merged with their phone and their laptop and their applications and everything.
The goal of Neuralink, then, is eliminating the middleman and putting that power we currently have at our fingertips directly into our brains. Instead of one person using their phone to transmit a thought to another person (“Dinner at 8?”), the thought would just go from one brain to the other directly.
Musk met with more than 1,000 people before decided on the eight who would help him shape the future of humanity at Neuralink. He claims assembling the right team was a challenge in and of itself, as he needed to find people capable of working in a cross-disciplinary field that includes everything from brain surgery to microscopic electronics.
The crew he landed is a veritable supergroup of smarties. They have backgrounds from MIT, Duke, and IBM, and their bios include phrases like “neural dust,” “cortical physiology,” and “human psychophysics.” They’re engineers, neurosurgeons, and chip designers, and if anyone can bring Elon Musk’s vision to life, it’s them.
