When we understand Caenorhabditis elegans intelligence, we will be at the beginning of the beginning of understanding human intelligence, maybe.

THE BRAIN-CIRCUIT EVEN THE SIMPLEST NETWORKS OF NEURONS DEFY UNDERSTANDING. SO HOW DO NEUROSCIENTISTS HOPE TO UNTANGLE BRAINS WITH BILLIONS OF CELLS? https://www.nature.com/articles/548150a

I wonder if our switch from analogue to digital computing is what makes this so very hard to model? I'm just spitballing wildly, as I know near nothing about neurons, but from what little I understood from a neuroscientist friend, neural signals propagate based on electric and chemical thresholds being reached, but then there's so many interactions that can amplify or reduce these things, and it all sounded rather like old school signal engineering to me (I used to hang out with radio engineers at an old job, and also listened avidly while understanding little).

One thing that stuck with me from the radio engineers is that something as commonplace as a Yagi antenna can't be fully modeled due the to sheer number of interactions, and developing new designs often requires an iterative trial and error approach.

Caveat - I was told this in the mid 2000s, so maybe it's changed since then.
