A laptop that looks like a thermonuclear explosion inside of a liter bottle of coca cola? Or a black hole? Read Seth Lloyd’s follow up to a Nature article that pushes Moore’s Law to the limit.… read more
The 5th Annual Edge Question reflects the spirit of the Edge motto: “To arrive at the edge of the world’s knowledge, seek out the most complex and sophisticated minds, put them in a room together, and have them ask each other the questions they are asking themselves.” Seth Lloyd asks: Is the universe a quantum computer?… read more
The amount of information you could process if you were to use all the energy and matter of the universe is 10^90 bits and the number of elementary operations that it can have performed since the Big Bang is about 10^120 ops. Perhaps the universe is itself a computer and what it’s doing is performing a computation. If so, that’s why the universe is so complex and these numbers say how big that computation is. Also, that means Douglas Adams was right (the answer is “42″).… read more
Machine consciousness may not be a matter of replicating total human thought capacity–it may come in several small, specialized parts. In this discussion with the Edge’s John Brockman, Pattie Maes discusses IA (Intelligence Augmentation) as opposed to AI.… read more
