Intelligence is a spectrum, although creativity is trickier to define. I would argue that most children grow up inventing their own methods of expression (usually pictorial), until they learn the existing mones well enough to communicate satisfyingly enough. The capacity and drive to create, perceive, and extend is innate.
Most humans have not spontaneously invented new usable alphabets, so I suppose that means most humans haven't meet the bar for true intelligence either.
I still don't understand this obsession for trying to define "hard AI" or "true intelligence" in binary terms. Intelligence is a spectrum, and deep learning has advanced it forward, thus making machines more intelligent -- yes, we can use that word 'intelligent' for computers just as we do for biological machines. Don't freak out.
Is it really so hard to accept that intelligence isn't all-or-nothing?
