AI is internally limited by model and externally limited by the environment.
Humans are externally limited by the environment but not necessarily internally limited by a computable model (as AI is).
So, humans may possess certain skills (e.g. creativity) that an AI may never possess. I had previously asked a related question https://ai.stackexchange.com/q/10139/2444.
Which research work supports my claims?
Brian Cantwell Smith says that there is no computation without representation (a model).
In the article The Brain Is Not Computable, Miguel Nicolelis, a top neuroscientist at Duke University, also says
The brain is not computable and no engineering can reproduce it
You can't predict whether the stock market will go up or down because you can’t compute it.
You could have all the computer chips ever in the world and you won't create a consciousness.
That's because its most important features are the result of unpredictable, nonlinear interactions among billions of cells
