The interview explores the self-organizing nature of neurons and brain cells, emphasizing how biological systems inherently carry instructions that guide their development and structure—without requiring detailed blueprints like in engineering. The discussion highlights how brain organoids (3D cultures of brain cells in a dish) can self-organize and even track developmental time with surprising accuracy, suggesting the existence of an internal biological clock that functions independently of the body.
