After more than 40 years of observing inventive artificial neural systems at work (i.e., Creativity Machines), I have found that they are susceptible to the very same cognitive pathologies as the brain. In fact, as such forms of synthetic psychology are pushed toward higher levels of creativity, the more likely they are to exhibit the classic psychopathologies, such as schizophrenia, manic-depression, and various attention disorders.

Finally getting up the nerve to solo publish within a culture well outside physics and computer science, I took my chances with Elsevier’s journal Medical Hypotheses, and was pleasantly surprised. After all, neurobiology obeys physics. So, if the biologists consider this the proverbial “spherical chicken in vacuum” then they should reconsider its power in providing a streamlined, bottom-up perspective on both the mechanics of seminal cognition and what can go wrong with that process. True, insanity and creativity have been known to positively correlate with one another for centuries, but I am offering the nuts-and-bolts model, using amazingly simple mathematical principles.

Thaler is an interesting guy although he is definitely going his own way in AI research.
From Next Big Future:

Artificial intelligence researchers claims sentient creativity machines will be made within 5 years
The AI researcher Dr. Stephen Thaler has given an interview recently in which he claims that his AI research will lead to sentient, cognizant "creativity machines" within 5 years.

The research continues to accelerate.

Consciousness appears to be more like an intensive rather than extensive property/behavior of the brain. It’s sort of like the gas law equation, PV= nRT, with P and T being intensive and n and V extensive. So, consciousness is intensive, but we as humans deny simpler forms of consciousness, while fearing the scaled up version attainable via machine intelligence.

Imagination Engines, Inc. was founded upon key scientific and engineering breakthroughs in the area of artificial neural networks by Dr. Stephen Thaler.
An Imagination Engine is a trained artificial neural network that is stimulated to generate new ideas and plans of action through a very amazing effect that is an outgrowth of scientific experiments conducted in 1975 by our founder, Dr. Stephen Thaler. In these initial experiments, neural networks were trained upon a collection of patterns representing some conceptual space (i.e., examples of either music, literature, or known chemical compounds), and then the networks were internally 'tickled' by randomly varying the connection weights joining neurons. Astonishingly...MORE
For the naysayers the practical results were good enough to land some Department of Defense and NIST funding.
Creative crazies, sounds about right.
