All opinions are my own:

The whole point of the CNNs is to act like a auto encoder for input and an auto decoder for output. The only reason why this is done in the first place is because the number of electrodes in the dish is pitiful and has no chance of describing something as complex as Doom. They are there to create a latent space that can be fed through 60 odd electrodes and decode the neuron latent space into pressing buttons.

The pong version of the game was the proof of concept that neurons can learn without a latent space intermediate in either direction. Both the world state and neuronal control were raw signals: https://pubmed.ncbi.nlm.nih.gov/36228614/

What I wanted to do after dish brain pong, but never had the budget for, was using live animals as the computational substrate. Use the visual cortex of one as the input, send the neural spikes to a second animals frontal lobe for computation and finally send those signals to a third animals motor cortex to physically press buttons. It's a shame we never raised enough because it wouldn't have cost more than $15m to build the hardware and do the biological proof of concept.

That sounds terrifying.

Reminds me of the head transplant experiments. The stuff of nightmares but also fascinating.

This sounds nightmarish. Maybe we build a human centipede if we can get the VC funding next?

What does the ethical due diligence process look like, for something like this?
