Some folks think life and technology and mind can keep expanding forever. Others say it can't. We are still not clear on that.
Seth LloydWhen you zap things with light to build quantum computers, you're hacking existing systems. You're hijacking the computation that's already happening in the universe, just like a hacker takes over someone else's computer.
Seth LloydI have not proved that the universe is, in fact, a digital computer and that it's capable of performing universal computation, but it's plausible that it is.
Seth LloydThe primary consequence of the computational nature of the universe is that the universe naturally generates complex systems, such as life. Although the basic laws of physics are comparatively simple in form, they give rise, because they are computationally universal, to systems of enormous complexity.
