Actually, it appears that most effective information exchange may not rely solely on spiking neurons. But it is non-spiking neurons, which effectively coarse-grain the signal, that seem to provide a more energy-efficient and information-rich strategy for the brain to perform its functions.
This is at complete odds with what Ilya proposes. It is *precisely* the multiscale dynamical structure that exists, not in parallel with, but *because of* metabolic costs of neural spiking (what @pessoabrain.bsky.social mentioned)..

that makes the brain, *brainy*.
I don't disagree, ANNs computational units might be good abstractions of neurons.
*But* this does not entail that the systems generated by them, are analogous too.
