There are many classes of problems in computer science and AI falls into one of my favorites.

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: how do you build smart software within realistic constraints.

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.

How do we develop intelligent systems when we don't know how to measure intelligence?

Who says we don't know how to measure intelligence? The simplest way would be just to select a problem that requires intelligence and measure how good it does at that problem.

"But how do we make a computer program that decides what it wants to do? How do we make a computer decide to care on its own about learning to drive a car? Or write a novel?" Perhaps it'd be better to ask: why would we want a computer to do these things? I certainly do not want to live in a world where computers have their own motivations and desires and the ability to act on the same. Actually, I can put that more s…

you seem pretty convinced living computers would kill us all. this seems like a pretty big assumption to me?

It's the same thing with aliens. The "evil, technologically superior alien race" is a big trope in science fiction, just as the "super-intelligent and malevolent" (as opposed to the super-intelligent and benevolent/indifferent) is in science fiction, and maybe even with futurists.

Critically speaking, this article doesn't add anything. I don't know why I read it. Can anyone explain why they upvoted?

It's well written. And I like the idea that maybe there is one algorithm. That'd be cool.

This is a serious issue. The notion of "intelligence" is so abstract and intangible, that giving it a concrete definition is nearly redefining it. Likely what we're calling intelligence, is an oversimplification of reality; somewhat akin to the species problem in biology.

Shane Legg (one founder of DeepMind, purchased by Google) has written a number of good papers around the "measuring machine intelligence" problem.

http://www.vetta.org/documents/Benelearn-UniversalIntelligen... is a pretty good place to start.

Infinite CPU seriously? I think if we had even a couple of orders of magnitude compute power we can have strong AI within a few years. It's not a hard problem at all. The limiting thing is compute power (and data to compute with).

Earlier quoted context omitted.

If you had a machine with infinite CPU power and infinite RAM you could _evolve_ an AI. Greg Egan wrote a great story about that: http://ttapress.com/553/crystal-nights-by-greg-egan/ Someone tries it, with mixed results.

Ah, but we weren't given infinite time also, so you might be able to evolve an AI, but it might take many millions of years (like it did with real life).

He said infinite CPU power which implies infinite number of iterations. In real life it would probably take a lot more than millions of years (because computers are too slow to simulate populations of millions of minds.)
