We've had this argument before so I'll summarize . . . . Knowledge compression may well be mostly equivalent with the "logical view" of AI. Text, however, can express the same knowledge in a near infinitude of different forms. Requiring an AI to decompress the same knowledge into a variety of different forms based upon what was input is a tremendously more difficult problem than AI without that requirement (and having that requirement doesn't seem to have any benefit). ----- Original Message ----- From: "Matt Mahoney" <[EMAIL PROTECTED]> To: <agi@v2.listbox.com> Sent: Tuesday, April 17, 2007 10:15 PM Subject: Goals of AGI (was Re: [agi] AGI interests) > On 4/17/07, James Ratcliff <[EMAIL PROTECTED]> wrote: >> >> A simple list, or set of goals for an AGI to accomplish reasonably I would >> find very useful, and something to work for. > > I think an important goal is to solve the user interface problem.
