For now, new full episodes are released once or twice a week and 1-2 new clips or a new non-podcast video is released on all other days.

Note: I select clips with insights from these much longer conversation with the hope of helping make these ideas more accessible and discoverable. Ultimately, this podcast is a small side hobby for me with the goal of sharing and discussing ideas. I did a poll and 92% of people either liked or loved the posting of daily clips, 2% were indifferent, and 6% hated it, some suggesting that I post them on a separate YouTube channel. I hear the 6% and partially agree, so am torn about the whole thing. I tried creating a separate clips channel but the YouTube algorithm makes it very difficult for that channel to grow. So for a little while, I'll keep posting clips on this channel. I ask for your patience and to see these clips as supporting the dissemination of knowledge contained in nuanced discussion. If you enjoy it, consider subscribing, sharing, and commenting.

Elon Musk is the CEO of Tesla, SpaceX, Neuralink, and a co-founder of several other companies.

We currently understand very little about the human brain.

Do you also hope that the work at Neuralink will help us understand more about the human mind, about the brain?

Yeah, I think the work at Neuralink will definitely shed a lot of insight into how the brain and the mind works.

Right now, just the data we have regarding how the brain works is very limited.

We've got fMRI, which is kind of like putting a stethoscope on the outside of a factory wall and then putting it all over the factory wall and you can sort of hear the sounds, but you don't know what the machines are doing really.

It's hard, you can infer a few things, but it's very broad brush stroke.

In order to really know what's going on in the brain, you have to have high precision sensors, and then you want to have stimulus and response.

Like if you trigger a neuron, how do you feel?

How does it change your perception of the world?

You're speaking to physically, just getting close to the brain, being able to measure signals from the brain will give us sort of open the door inside the factory.

Being able to have high precision sensors that tell you what individual neurons are doing and then being able to trigger the neuron and see what the response is in the brain so you can see the consequences of if you fire this neuron what happens how do you feel what does it change It'll be really profound to have this in people because people can articulate their change, like if there's a change in mood, or if they can tell you if they can see better or hear better, or be able to form sentences better or worse or,
