Maybe I wasn’t explicit about this point, but I’m not only talking about understanding the biological processes behind a neuron. I’m also talking about our ability to manipulate them in something like an industrial process, combining them with hardware in a controlled way and achieving reliable results.

Cells have a metabolism, right? They need to be fed and require a specific environment to survive. They age and can die, and they can be attacked by other microorganisms. Are all of these problems solved and applicable on an industrial scale? I had no idea.

Why aren’t we fixing people’s retinas and paraplegia if we can manipulate neurons with that level of precision?
