Ick. Triple negative (deny, not, different). It makes that sentence very hard to read.
I’m not an expert, but there must be a fundamental difference, or we’d have emulated a brain by now. A brain isn’t just neurons, it’s also chemicals. Our brains work differently depending on which chemicals are flowing through them. In addition, our brain is integrated with our body to the point where if we lose a limb, we still think it’s there. We can be convinced that a rubber hand is our own.
As I said previously, I don’t think it’s sufficiently different that parts of it can’t be emulated, augmented (as the technology in question purports to do), or even replaced entirely with electronic circuitry. I do think that it’s a profound oversimplification to say that there’s no fundamental difference between the two, because we’re approaching the nano-scale physical limits of how small we can make silicon-metal computer chips, and we still can’t fit anything resembling a human brain simulation into something the size of a human head, or something a thousand times that size even.
