      A trend that's incredibly misleading and frankly braindead: comparing the number of neurons in animals (C. elegans, honeybee, marmoset...) with the number of "neurons" in an ANN (which is the sum of the dimensionalities of the intermediate spaces you use for affine projections)

      We used to compare the number of transistors on a chip to the number of neurons in the brain. Now we use the total number of filters in the Conv2D layers of a DL model for that comparison. It makes as much sense (which is none).

          Btw GPUs have 10-15B transistors these days, growing by 10x in ~5 years. So GPUs should be brain-scale in less than 5 years

          Probably it doesn't even make sense to compare two NNs by the number of their neurons/layers. I mean, there are simple MLPs where optimizers can find countless permutations of hidden neurons/layers that may perfectly work just fine for a given task. They're just nodes/parameters.

          That is correct, in particular it doesn't make sense across different architectures
