<s>[INST] Have you seen evidence that the technology is actually working, that you've got a richer, sort of, higher bandwidth connection, if you like, between like external electronics and a brain than has been possible before? [/INST] Yeah. I mean, the fundamental principles of reading neurons, sort of doing read-write on neurons with tiny electrodes, have been demonstrated for decades. So it's not like the concept is new. The problem is that there is no product that works well that you can go and buy. So it's all sort of, in research labs. And it's like some cords sticking out of your head. And it's quite gruesome, and it's really ... There's no good product that actually does a good job and is high-bandwidth and safe and something actually that you could buy and would want to buy. But the way to think of the Neuralink device is kind of like a Fitbit or an Apple Watch. That's where we take out sort of a small section of skull about the size of a quarter, replace that with what, in many ways really is very much like a Fitbit, Apple Watch or some kind of smart watch thing. But with tiny, tiny wires, very, very tiny wires. Wires so tiny, itís hard to even see them. And it's very important to have very tiny wires so that when theyíre implanted, they donít damage the brain. </s>
