…Okay. So going slowly towards Neuralink, one interesting question is, what do we understand on the BCI front, on invasive versus non-invasive, from this line of work? How important is it to park next to the neuron? What does that get you? That answer fundamentally depends on what you want to do with it. There’s actually incredible amount of stuff that you can do with EEG and electrocortical graph, ECOG, which actually doesn’t penetrate the cortical layer or parenchyma, but you place a set of electrodes on the surface of the brain. So the thing that I’m personally very interested in is just actually understanding and being able to just really tap into the high resolution, high fidelity, understanding of the activities that are happening at the local level. And we can get into biophysics, but just to step back to use analogy, because analogy here can be useful, and sometimes it’s a little bit difficult to think about electricity. At the end of the day, we’re doing electrical recording that’s mediated by ionic currents, movements of these charged particles, which is really, really hard for most people to think about. But turns out, a lot of the activities that are happening in the brain and the frequency bandwidth with which that’s happening, is actually very, very similar to sound waves and our normal conversation audible range. So the analogy that typically is used in the field is, if you have a football stadium, there’s a game going on. If you stand outside the stadium, you maybe get a sense of how the game is going based on the cheers and the boos of the home crowd, whether the team is winning or not. But you have absolutely no idea what the score is, you have absolutely no idea what individual audience or the players are talking or saying to each other, what the next play is, what the next goal is. So what you have to do is you have to drop the microphone into the stadium and then get near the source into the individual chatter. In this specific example, you would want to have it right next to where the huddle is happening. So I think that’s kind of a good illustration of what we’re trying to do when we say invasive or minimally invasive or implanted brain computer interfaces versus non-invasive or non-implanted brain interfaces. It’s basically talking about where do you put that microphone and what can you do with that information. So what is the biophysics of the read and write communication that we’re talking about here as we now step into the efforts at Neuralink?…
