Look up Piet Mondrian. Generally considered an artist. Got copied by computers back in the 1960's. Got copied well enough to fool experts.

So, if there is a Turing test for art, it got passed nearly 60 years ago.

The term Artificial Intelligence, we understand artificial it just means man-made. When it comes to intelligence we are out of luck. We can't sit down and give a cogent explanation of what it is. That's is pretty damn weird! Think about it for a minute. We recognize intelligence easily enough, we all have friends who need to work harder than we do to 'get' stuff and we all know some folks who make us look slow on the up-take.

One argument I make is that if we don't know what Natural Intelligence actually is, then everything we say about AI is more than likely BS! How likely is it that random crap is correct?

I can't define intelligence better than anyone else but since I can, like all of us, identify it then I pick mathematics as a stand-in for intelligence. Why math? Because it is the only unbroken line of development of intellectual history available as far as I know. Our first written math comes Mesopotamia and Egypt from 2,000 BC. 4,000 years of hard fought progress. Earlier stuff is lost to us but we know that math and art started roughly at the same time: Rock paintings of hunting scenes and bones with notches that may be counting sticks, or not. What is assumed to be a five count, four uprights and a diagonal, could just as easily be a pictograph of a hand holding a spear.

We spend 12 years in school to learn 4,000+ years of research. Just the very basics, nothing later than 1800 or so. Essentially just one long survey course. Higher education beckons and we learn some things in depth. Some even add another brick to the pile.

The takeaway is than 1980's AI pet Expert Systems were essentially a Rube Goldberg version of 20+ questions. Today's version is sophisticated pattern matching. Both are likely threads in what make up the tapestry of intelligence. That is just raw materials. Then we have to consider the machinery. And finally the 'ghost in the machine', the weaver.

AI turns 75 in two years. It will get a hell of a lot older before it gets 'intelligent'.
