Hinton's mature position (Lillicrap et al. 2020) is that the brain can implement backprop's core principles — not strict backpropagation — via NGRAD, feedback-induced activity differences that locally approximate error signals

Capture: Did Crick (1989) 'The recent excitement about neural networks' (Nature 337:129–132) first formally state the weight transport problem, predating Hinton's 2022 formulation?

Capture: What is Hinton's exact qualified position on the brain approximating backprop, as stated in Lillicrap et al. (2020) 'Backpropagation and the brain,' NRN 21(6)?

Feedback alignment shows fixed random feedback weights can train networks to near-backprop accuracy — but whether it "is" backpropagation is disputed
