AIXI shows a couple interesting things... -- truly general AI, even assuming the universe is computable, is impossible for any finite system
-- given any finite level L of general intelligence that one desires, there are some finite R, M so that you can create a computer with less than R processing speed and M memory capacity, so that the computer can achieve level L of general intelligence This doesn't tell you *anything* about how to make AGI in practice. It does tell you that, in principle, creating AGI is a matter of *computational efficiency* ... assuming the universe is computable. The computability of the universe is something that can't really be proved, but I argue that it's an implicit assumption underlying the whole scientific method. If the universe can't be usefully modelable as computable then the whole methodology of gathering finite datasets of finite-precision data is fundamentally limited in what it can tell us about the universe ... which would really suck... -- Ben G -- Ben G On Sat, Oct 25, 2008 at 7:21 PM, Matt Mahoney <[EMAIL PROTECTED]> wrote: > --- On Sat, 10/25/08, Mark Waser <[EMAIL PROTECTED]> wrote: > > > Ummm.
