It's nice that someone now has the neural wiring diagram for part of a mouse brain. But we have the full wiring for a thousand-cell nematode, and OpenWorm still doesn't work very well.[1] OpenWorm is trying to get a neuron and cell level simulator for what's close to the simplest creature with a functioning nervous system - 302 neurons and 85 muscle cells. That needs to work before moving to more complexity.
