Well, if there's one thing we're pretty sure of about human cognition, it's that there's very few GPUs in a human brain, on account of the very low percentage of sillicon. So, in a very very direct sense, we know for sure that human brains don't work like LLMs. Now, you could argue that, even though the substrate is different, some important operations might be equivalent in some way. But that is entirely up to you to argue, if you wish to. The one thing we can say for sure is that they are nothing even remotely similar at the physical layer, so the default assumption has to be that they are nothing alike period.
