13 years ago, I walked into Dr. Stuart Hameroff’s operating room with a camera, a microphone, and a single stubborn question:
Is consciousness computation?
Hameroff, an anesthesiologist and professor at the University of Arizona, and co-author with Sir Roger Penrose of the Orch OR theory, said no.
Emphatically. Unfashionably. Against the entire weight of mainstream neuroscience and Silicon Valley orthodoxy.
At the GF2045 conference, where I first met him, Ray Kurzweil went out of his way to declare Orch OR “totally wrong.” Others called it speculative. Untestable. Unscientific.
Today, in the age of large language models, that argument is no longer a niche dispute among philosophers and physicists. It is the decisive question of our century.
If consciousness is computation, machines will eventually wake up. If it isn’t, they never will, no matter how large the model or how clever the architecture.
Hameroff’s position is uncomfortable precisely because it is testable, falsifiable, and biologically rooted. A neuron, he insists, is not a switch. It is a cell, woven with microtubules, possibly hosting quantum events that no classical computer can replicate.
His most haunting line still stops me cold:
“Consciousness is the music of the universe.”
Not its arithmetic. Not its byproduct. Not an emergent illusion to be optimized away.
You can disagree with the theory. Many brilliant people do.
But you cannot disagree with the stakes.
Because if Hameroff is right, then every promise of digital immortality, machine sentience, and uploaded minds is built on a category error we have not yet caught.

Dr. Stuart Hameroff is a Professor of Anesthesiology and Psychology and Director of the Center for Consciousness Studies at the University of Arizona. Together with British quantum physicist Sir Roger Penrose, Hameroff is the co-author of the controversial Orch OR model of consciousness.
I first met Dr. Hameroff at the recent GF2045 conference where the usually mild-mannered Ray Kurzweil went out of his way to make it abundantly clear that the Orch OR model is totally wrong. Others called it “speculative,” “non-testable” and “unscientific”. By now both Stuart and Roger must have become accustomed to such attacks, and I have developed a lot of respect for the calm but firm way they are daring to stand their ground. Furthermore, if the Orch OR model were to be correct, then, there will be profound implications on a variety of fields and disciplines such as medicine, neuroscience, artificial intelligence, quantum physics, and philosophy. And so I decided to bring Dr. Hameroff on Singularity 1 on 1 where we can confront the controversy head-on.
