> Farm animals grown with their brains shut off, used as compute substrate for biological neural networks, while their biological functions are controlled remotely.

I’m sorry, you were working on what? Where does one learn more about this concept?

>Where does one learn more about this concept?

One does not.

One builds the tools to run the experiments to discover the rules.

The closest are FinalSpark and CorticalLabs, but they both are only using in vitro neurons as the computational substrate.

Neuralink et al. are working in vivo, but they are only doing output and don't have any plans to do input, let alone to actively disrupt normal neural activity and take control of bodily processes.

If you're very interested feel free to drop me a line.
