The "correct" one is http://pobox.com/~sentience/AI_design.temp.html, which forwards to the one you mentioned.

I've been thinking about that a lot. (Naturally - it *is* my lifegoal.) It strikes me that while designing is all well and good, I have to make sure there's an Internet capable of running it and a programming community capable of coding it. Right now, the hardware industry is in serious jeopardy because Bill Gates is starting to default on his promise of sucking up all the CPU cycles Intel can give him, and thesoftware industry can't do anything whose complexity is above a certain limit without it starting to look like something out of the Slow Zone.
To build that AI I need three things: Massive hardware backed by Internet-2 and a distributed.net to pull it together; OpenSource volunteers with the ability to write a new kind of software; and the computer-community will to do it. I'm mostly working on (1) and (2). Which in turn requires that I shove the entire computing community in a certain direction, the direction of scalable software.
Scalable software is software that gets qualitatively better, not just faster, when you give it more computing power. Deep Blue and EURISKO are scalable software, but for scalable software to keep Intel in the money (to pump out the hardware I need), scalable software has to get into word processors and accounting programs, and that means a new kind of software design.
So now I'm working on designing a computer language in which you can write that kind of software; furthermore, a language that can eventually mature into something in which we can write Elisson. The next great transition, the successor to object-oriented programming as OOP replaced structured programs - adaptive code.

AIs do need sensory environments to ground their thoughts, but not artificial environments; they're already native to a sensory environment richer than any of us have ever seen. What is the most elegant, beautiful, complex domain humanity has ever found? Code.

Marr gets major kudos for pre-inventing the concept of domdules, but what we need is not 2.5D vision; we need 2.5D code.
