alt Hacker NewsI suspect you're being snarky :-) but this is a really interesting question, and one that has had a lot of research done. I'm not current (I stopped following folks doing this research closely around 2019) but what we 'didn't' know about how brains work was still huge. Signaling levels, enzymes, the connectome, quantum effects, it is a really deep question.
That said, once we do get a working idea of how it works, and can perhaps synthesize a brain artificially with proteins, it will inform us on the next steps for silicon realization of that.
I think the point is that tremendous complexity can arise from relatively simple mechanisms. That is what life is, at many levels. I’m not at all convinced that the current LLM approach will yield something we can broadly call consciousness but saying that it’s a simple concept and therefore won’t support consciousness is a specious argument imo.
