Geometry of Brain Activity and Donut Topology

Dr. Erik Bekkers is an associate professor in Geometric Deep Learning at the University of Amsterdam, an ELLIS Program Director, and one of the most original thinkers working at the intersection of mathematics, AI and consciousness.

He reverse-engineered how the human visual cortex processes reality using the geometry of curved spaces — then used those same principles to build AI architectures that outperform standard deep learning. He recently published a paper arguing that AI will never be conscious, introducing a framework called Biological Idealism.

Expect to learn why your brain lifts reality into a higher-dimensional space just to see a straight line, what autopoiesis is and why it might be the dividing line for consciousness, why psychedelics decreasing brain activity while increasing experience is a problem for materialism, why firing neurons are an appearance of experience not the cause of it, why AI leaders claiming machines might be conscious is dangerous, and much more
