Artificial intelligence pioneer says we need to start over

The bottom line: Other scientists at the conference said back-propagation still has a core role in AI's future. But Hinton said that, to push materially ahead, entirely new methods will probably have to be invented. "Max Planck said, 'Science progresses one funeral at a time.' The future depends on some graduate student who is deeply suspicious of everything I have said." How it works: In back propagation, labels or "weights" are used to represent a photo or voice within a brain-like neural layer.
