Like I stated at the beginning, *most* models are at least theoretically valid. Of course, tractable engineering of said models is another issue. :-) Engineering tractability in the context of computer science and software engineering is almost purely an applied mathematics effort to the extent there is any "theory" to it, and science has a very limited capacity to inform it.

If someone could describe, specifically, how to science is going to inform this process given the existing body of theoretical work, I would have no problem with the notion. My objections were pragmatic.

Now hold on just a minute.

Yesterday you directed the following accusation at me:

You *vilified* the claim that I made, and implied that I could only say such a thing out of ignorance, so I challenged you to explain what exactly was the science behind artificial intelligence.

But instead of backing up your remarks, you make no response at all to the challenge, and then, in the comments to Ben above, you hint that you *agree* that there is no science behind AI ("... science has a very limited capacity to inform it"), it is just that you think there should not be, or does not need to be, any science behind it.

So let me summarize:

1)  I make a particular claim.

2)  You state that I can only say such a thing if I am ignorant.

3)  You refuse to provide any arguments against the claim.

4)  You then tacitly agree with the original claim.


Oh, and by the way, a small point of logic. If someone makes a claim that "There is no science behind artificial intelligence", this is a claim about the *nonexistence* of something, so you cannot demand that the person produce evidence to support the nonexistence claim. The onus is entirely on you to provide evidence that there is a science behind AI, if you believe that there is, not on me to demonstrate that there is none.
