The physicist who led design of the first commercial microprocessor had a 1990 experience that upended his materialist worldview; he now argues, with a physicist collaborator, that consciousness is fundamental to reality.
The line above is how his claims were received — by the scientists whose job was to doubt them. It rises as a claim is tested and accepted, and the room brightens with it. It is not a verdict on truth: some accepted ideas are later overturned, and some rejected ones come back. A hollow point is a claim still open.
As a young engineer at Intel, Faggin led design of the 4004, the first commercial microprocessor, after inventing the silicon-gate process that made it manufacturable — work later recognized with the 2010 National Medal of Technology and Innovation.
Following a 1990 experience he describes as a sudden burst of light and love that upended his materialist worldview, Faggin and physicist Giacomo Mauro D'Ariano proposed Quantum Information Panpsychism: that consciousness is a fundamental, quantum property of reality, not a brain product.
The theory remains speculative and, so far, untestable by mainstream physics; physicist Sean Carroll has argued more broadly that known physics leaves no causal room for consciousness as a new ingredient in nature. Faggin continues developing the framework in his 2024 book Irreducible.
