With infinite CPU power and infinite RAM, fully general artificial intelligence is a trivial problem (see: Marcus Hutter's AIXI). AI is an optimization problem

  AI is a software problem as well as a hardware problem. It's ridiculous to assume we understand the underlying model of the function of the human brain in general. We don't even understand the physics of it all yet. Be optimistic about AI, but don't be fooled -- it's not as basic as hooking up transistors and thinking they behave like neurons.

    Theoretically maaku is right. With infinite RAM and CPU you would just have to execute every random string of bytes until one of them happens to be strong AI. Of course, there's probably less than 1% chance of it being friendly...

      But how would you recognize those bytes?

        How do you define intelligence?

          Optimization power, possibly divided by available resources. In a game of Chess, only a narrow set of moves will let me steer the future into a winning state. Well, the same is true for the Game of Life (the real one, not Conway's): we humans are intelligent because we're able to steer the future through probability to a-priori incredibly unlikely outcomes. Compare walking vs moving your limbs randomly.

            It was a rhetorical question. The point was once you have a definition of intelligence - yours is one of many fine definitions - you can refine that into a metric for comparing different intelligences, and then you have a way for a comparison function given two program descriptions to determine which is "more intelligent". Building artificial intelligence then reduces to undirected search, assuming infinite CPU and RAM.

              Well, if we do that and succeed, we're all dead.
