  I present my recollections of Richard Feynman's mid-1980s interest in
artificial intelligence and neural networks, set in the technical context of
the physics-related approaches to neural networks of that time. I attempt to
evaluate his ideas in the light of the substantial advances in the field since
then, and vice versa. There are aspects of Feynman's interests that I think
have been largely achieved and others that remain excitingly open, notably in
computational science, and potentially including the revival of symbolic
methods therein.
