In theory, you could actually basically print pretty much anything. Anything that we can make that's a physical structure to combat those physical structures will probably get made over the next 20, 30, forty years. The world would be using solar energy instead of carbon dioxide or natural gas. We're running on a very tiny amount of energy and we're using a massive amount of energy in this process. So clearly, the algorithms we're using in theworld are not algarms that Al Gore is using. This is like a quadrillions x watsoflion competition with nature. It's what it comes down to.
