2 Aug 2024 Lex Fridman Podcast #438 – Elon Musk: Neuralink and the Future of Humanity

“The more sophisticated higher level processing areas like the Broca’s area or Wernicke’s area, those are still very, very big mystery in terms of the underlying mechanism of how all that stuff works. But I mean, I think Neuralink’s eventual goal is to understand those things and be able to provide a platform and tools to be able to understand that and study that.”

Transcript context

…Yeah. It’s really cool how the app that Noland is using, there’s calibration, all that kind of stuff, and then there’s update. You just click and get an update. What other future capabilities are you looking to? You said vision. That’s a fascinating one. What about accelerated typing or speech, or this kind of stuff? And what else is there? Yeah. Those are still in the realm of movement program. So, largely speaking, we have two programs. We have the movement program and we have the vision program. The movement program currently is focused around the digital freedom. As you can easily guess, if you can control 2D cursor in the digital space, you could move anything in the physical space. So, robotic arms, wheelchair, your environment, or even really, whether it’s through the phone or just directly to those interfaces, to those machines. So, we’re looking at ways to expand those types of capability, even for Noland. That requires conversation with the FDA and showing safety data for if there’s a robotic arm or a wheelchair, that we can guarantee that they’re not going to hurt themselves accidentally. Right? It’s very different if you’re moving stuff in the digital domain versus in the physical space, you can actually potentially cause harm to the participants. So, we’re working through that right now. Speech does involve different areas of the brain. Speech prosthetic is very, very fascinating and there’s actually been a lot of really amazing work that’s been happening in academia. Sergey Stavisky at UC Davis, Jaimie Henderson and late Krishna Shenoy at Stanford, are doing just some incredible amount of work in improving speech neuro-prosthetics. And those are actually looking more at parts of the motor cortex that are controlling these vocal articulators, and being able to, even by mouthing the word or imagine speech, you can pick up those signals. The more sophisticated higher level processing areas like the Broca’s area or Wernicke’s area, those are still very, very big mystery in terms of the underlying mechanism of how all that stuff works. But I mean, I think Neuralink’s eventual goal is to understand those things and be able to provide a platform and tools to be able to understand that and study that. This is where I get to the pothead questions. Do you think we can start getting insight into things like thought? So, speech, there’s a muscular component, like you said, there’s the act of producing sounds, but then what about the internal things like cognition, like low-level thoughts and high-level thoughts? Do you think we’ll start noticing signals that could be picked up, they could be understood, that could be maybe used in order to interact with the outside world?…
