In my opinion, the work of J.J. Hopfield and G.E. Hinton is extraordinary, but I don't think it was a good decision by the Nobel Committee in Physics. To begin with, it was Warren McCulloch and Walter Pitts who first proposed neural networks. To continue, this work has only a lateral relationship to physics, even though the Committee argues that it has to do with atomic spin. This is not true: at best it may be an ‘inspiration’ to consider that the union of several processing units (artificial neurons) can contain and store distributed information. My impression is that the committee's decision has more to do with AI being an important and ‘fashionable’ field, and less to do with the contribution to physics of the laureates.
