Elon Musk @elonmusk on Neuralink:

“So, when I emphasized the purpose of Neuralink, like what do we, what's our goal, our goal is to solve important spine and brain problems with a seamlessly implanted device. So, you wanna have a device that you can basically put in your head and feel and look totally normal, but it solves some important problem in your brain or spine. And the reality is that almost everyone, over time, will develop brain and spine problems. These range from minor to very severe, but if you live long enough, everyone's gonna basically have some kind of neurological disorder, from memory loss to brain damage. But the thing that's important to appreciate is that an implantable device can actually solve these problems. I think a lot of people don't quite realise that, but all of your senses, your sight, hearing, feeling, pain, these are all electrical signals sent by neurons to your brain.”
