The Scientist Who Taught Machines to Learn

Geoffrey Hinton pursued artificial neural networks through decades when the approach was widely dismissed. After studying experimental psychology at Cambridge and earning a doctorate in artificial intelligence at Edinburgh, he worked in California, Carnegie Mellon, Toronto and London. His research on Boltzmann machines, backpropagation, distributed representations and deep belief networks prepared the way for the 2012 ImageNet breakthrough. This documentary follows the path to the Turing Award and 2024 Nobel Prize.

Modern systems for recognizing images, processing speech and generating language depend heavily on neural-network ideas that Hinton helped preserve and develop. His career shows how a rejected research direction can become a technological foundation once theory, data and computing power align. It also has a profound final turn: after helping create the field, Hinton left Google to speak more freely about AI's dangers. This documentary connects scientific persistence, global transformation and urgent ethical debate.
