I’d say it’s clear since we continue to make significant progress in replicating the behaviour of biological NNs with the main limitation being the amount of parallelism we can throw at it. If you read closely I stated that our model of the neuron may require modification but the basic idea is correct. Our implementation of artificial NN is in its infancy, we still don’t fully understand how to structure these networks and the way we feed them data is nowhere close to how biological NNs get theirs from the environment but the current SOTA is necessary because we don’t know how to build something capable of operating in the same way. We still have a lot to learn. We’re competing with hundreds of millions of years of evolutionary exploration using our fairly rudimentary understanding of biology. 60 years is nothing especially considering progress is not inevitable and this area of science has major boom and bust cycles where not a lot gets done.
