And we have a complete wiring diagram for C. elegans, and no clue how it does any of the things you talked about. So, yeah, general AI is really far off.
To be honest, the wiring diagram is a bit of a distraction from the really big questions. It has its uses for sure, and is really essential in many situations but overall it gives this illusion that we understand something important about the system, where in reality we don't. Understanding a biological system from its wiring diagram is something like understanding a city by studying its road map.
I have no idea what I'm talking about. But why couldn't we build some sort of bio-computer hybrid system around a simple form of life, like "C. elegans" but augmented with traditional CPUs?
