If players can give the AI fedback about what they're experiencing in real time, it can learn what works and what doesn't for building 3D worlds/games for us to experience at a faster rate. E.G. We're hooked up to a feedback device that lets it know if we like what we're seeing. Or just a few buttons on the screen we can press to let it know what we think. Click on the object in the room that's out of place or looks weird and let it know that's not right.
