To say that we have to exactly copy a human brain to produce true intelligence, if that is what Knapp and Stross are thinking, is anthropocentric in the extreme. Did we need to copy a bird to produce flight? Did we need to copy a fish to produce a submarine? Did we need to copy a horse to produce a car? No, no, and no. Intelligence is not mystically different.
I think he doesn't understand what those people are saying. Nobody doubts that you don't need to imitate human intelligence to get artificial general intelligence but that a useful approximation of AIXI is much harder than understanding human intelligence.
AIXI is as far from real world human-level general intelligence as an abstract notion of a Turing machine with an infinite tape is from a supercomputer with the computational capacity of the human brain. An abstract notion of intelligence doesn’t get you anywhere in terms of real-world general intelligence. Just as you won’t be able to upload yourself into the Matrix because you showed that in some abstract sense you can simulate every physical process.

I periodically get email from folks who, having read "Accelerando", assume I am some kind of fire-breathing extropian zealot who believes in the imminence of the singularity, the uploading of the libertarians, and the rapture of the nerds. I find this mildly distressing, and so I think it's time to set the record straight and say what I really think.
Short version: Santa Claus doesn't exist.

EDITED TO ADD: don't get your hopes up, this is pretty weak stuff.
