Obviously, cultural differences exist. Religious differences exist. There's all kinds of local cultural stuff, but people are the same. So the important part is to figure out how do we find ways to reach across the aisles? And so one of my... Big interests is if I can get to the right ears, the right place to tweak the social media algorithms. So here's what I mean.

Currently, as we all know, the social media algorithms favor anger and it's incentivized to be incendiary, let's call it. But here would be the optimal social media algorithm that I think could actually change the world is imagine that you and I have totally different political beliefs. But we both like hang gliding and this kind of dog and we like biking on Sundays and whatever.

So every time one of us makes a post on that, we're both seeing that. I don't know you yet. You're a stranger to me, but I see that post and you see my post. Oh, hang gliding. Oh, this. We find all these things that we have in common. Then one day when we discover, oh, we have different political opinions, then we're like, oh, cool, Jordan, tell me about that. Why do you feel that way? And so on.

Then we can talk. But if the first thing you know about me is that I have a different political opinion, then it's a different ballgame.

Exactly right. And by the way, it doesn't have to be the in-group everybody. It's my in-group is other hang gliders and other people who like this kind of dog. Like, that's my only group. That's fine, because there's nothing about that that's going to make me pick up arms and go to war over that stuff.

Exactly. Exactly right. And by the way, obviously these social media companies from our behavior and things we post, they know hundreds of data on us. So that can really be used for good by saying, hey, look, these two strangers have something in common that they like. Just whatever. We like Salvador Dali paintings or whatever it is.

Yeah. So, okay. The short answer is right now, we don't have the technology that would even get us close to that. Why? Because the brain is made up of 86 billion neurons, about that same number of glial cells. And the connections between the neurons is about 200 trillion synapses, the connections between them. Okay. What does that mean?
