When was the last time you got to sit down and discuss some really big ideas? And not scale big, like Facebook and Twitter. And not even industry-shifting big, like Kickstarter and Simple. No, let's talk even bigger. Asteroid mining. Underwater cities. Teleportation. Radical life extension. Let's free ourselves to imagine a bigger, brighter world, beyond the practical constraints of our daily work. In this conversation we will throw away all of our pre-conceived notions of what is possible and talk instead about why we should want these things. We will use our actual brains to think about the world as we want it to be and, along the way, we might just discover some practical paths to get there.
