Artificial Intelligence - What Is It, After All?

Yeah, by the way: what is the definition of AI?

Computer with 10^10 simple proceccors connected in a brain neuron network manner? Then we do not have AI yet (but it is coming, as we now have technology to pack about 10^9 transistors on one 1x1 cm^2 chip, and a complexity of a single neuron in most cases is equivalent to less than 100-transistor circuit). Somebody predicted that in 10 years supercomputers will be as powerful as average brain, and that in 20 years - $1000 PC will be as powerfull too.

Tracing emergence of intelligence with the evolution of brain, we may notice that even very primitive animals or incects have some aspects of intewlligence: they can learn (mostly the same way we do - by trial-and-error), they can analyze situation before making important decision (to bite or not to bite), they have some memory, they can communicate with each other (by sound, body language, chemicals).

There are various databases around, and some of them can learn and even conversate with a human(like Hal software mentioned above).

Computer games - are they an example of AI?

The fact that 512-processor supercomputer Deep Blue could finally beat Garry Casparov in 1997 in chess - is it a sign that now a computer is smarter than a human in chess? (By the way, the Deep Blue analyses about 10^8 positions per second, while Garry - only 3).

Different software expert systems control air, train and car traffics, as well as various electronic traffics in banking and commerce, they search for oil and minerals, they optimize layout of millions elements on a computer chip, they help doctors to diagnose, and librarians to find blurry defined information. Even when you press numerous "search" buttons browsing the Internet, you engage numerous search and expert engines. So artificial intelligence systems are already there, making as "intelligent" decision as they can at your command.

There is software to create poetry and prose, to create and to play music, to draw and to paint, to create unusual 3-d sculptures.

So, what is intelligence, after all? And what is "artificial" one?
