I mean, I'm not arguing anything other than your false equivalent. I'm sure, at some point, we'll be able to mimic how the human brain actually works, not just imitate the results. But we're not even close right now. Not in the same ball park. Not in the same tri-state area. We still don't really understand how it does what it does completely. We know some of the processes, and understand that's it's chemicals interacting with the meat in some way, but it's still mostly kinda just weird stuff our body does. We're mostly just pointing at areas that light up with activity when we do a thing and saying "yep, that's the general area that's doing stuff."

And that's just understanding it, let alone figuring out how to imitate it with technology. And none of those parts of the brain work independently. They're spread out and they overlap and exchange and change information constantly, all with chemicals. Getting a computer to mimic the outcome is still something we're far from, but without the same processes, its not really gonna come out the same. We've got just... so long to go before we actually get close to simulating a human brain.

And just for fun, I do think this line of yours is funny:

The idea that the human brain is special is ludicrous and completely without evidence

Again, I wasn't saying anything of any sort, and I'm still not really taking any stance beyond "that shits complicated and we're not there yet." But you're supposing that a "synthetic implementation can achieve the same thing." ... without supporting evidence. This argument was clearly meant for someone else, but it's not really fair to demand evidence from someone for their claim when you don't support your own. Jumping to the conclusion that something is impossible is the same as assuming it's definitely possible. You don't know that. I don't know that. No one really knows that until it's done.
