> Yes we do. We know how neurons communicate, we know how they are formed, we have great evidence and clues as to how this evolved and how our various neurological symptoms are able to interact with the world. Is it a fully solved problem? no. It's not even close to fully solved. We're still figuring out basic things like the purpose of dreams. We don't understand how memories are encoded or even things like how we process basic emotions like happiness. We're way closer to understanding LLMs than we are the brain, and we don't understand LLMs all that well still either. For example, look at the Golden Gate Bridge work for LLMs -- we have no equivalent for brains today. We've done much more advanced introspection work on LLMs in this short amount of time than we've done on the human brain.
