That is also my impression.

Passing the Turing Test seems to me to be a sufficient (though not necessary) condition for intelligence. If a machine can jump through all the hoops which I am able to conure up, then I would consider it to be intelligent; indeed, much more so than the average human being.
This, of course, is not meant as a scientific test for intelligence. It is a sociological test for intelligence, which is apt, because the word "intelligence" as it is normally used has more sociological meaning than scientific. In particular, we say that someone is "very bright" if they seem able to jump through all the intellectual hoops which we've seen them encounter in everyday life.

I've generally been very disappointed in books I've read that are specifically about artificial intelligence. This includes Penrose's first book, which was terrific when he wasn't talking about intelligence, and pretty bad when he was. "Goedel, Escher, Bach" was pretty good.
Only two books spring to mind as being especially worthwhile reads among the books I've read on the subject:
Minsky's "Society of Mind" (1985) had a considerable influence on the way my thinking has developed. However, I read it as an impressionable, none-to-critical twelve year old, so I'm not sure how it has dated. Definitely worth a look.
Ray Kurzweil's "The Age of Intelligent Machines" (1990?) was a good read. A little dated now, it still contains a considerable amount of useful information, and some thought-provoking points.
I've "read", to varying degrees, a couple of dozen other books which are either directly about AI, or which touch on it as a major theme. Even the worst manage to stimulate some thoughts, but I recommend shorter essays or sf novels as being just as stimulating. Daniel Dennett seems to be entertaining and thought-provoking, although I haven't read much of his material.

That would be useful. One of the advantages of (two-way) hypertext is that these essays could stand on their own, while still being an integral part of a >H FAQ.
