I remember as a teen seeing a video where they put a rat brain on a microchip and trained to to fly planes in a flight simulator

Since reading that I never understood why the idea didn't get bigger.

Not a fan of using human brains for this... there's some serious ethical questions we need to untangle there.

Edit: I guess I never realized there's nothing stopping me from just doing this myself now. I could probably get this to connect to a raspberry pi that I have sitting around... How do I get rat brain cells though?

Edit 2: This looks more complicated than I wanted it to be https://www.youtube.com/watch?v=bEXefdbQDjw

Stupid science. Nature did this all on its own in a cave in the desert and we can't make this work in a lab?

The real trick will be in figuring out some sort of solid state device - probably at least partially (if not predominantly) analog, not digital - that can reliably mimic the behaviors of biological neurons.

The actual breakthrough of AGI isn’t going to occur until we figure out how to do machine learning with analog circuit design. Digital simply does not scale well - what we’re doing now with “AI” using GPUs is simply brute forcing the problem by layering dozens of markov chains on top of each other.
