> Nothing more.

You can say that about everything in a human brain. Neurons fire electric charges in response to inputs, nothing more. Ion channels do this, this neurochemical level rises, this chemical bonds to that receptor, nothing more. It's almost a version of 'reductio ad absurdum' but instead like you're saying "if I can explain how it works then it doesn't work".

OK it's statistical. Instead it could be determinsitic, or random. What other options are there for a human predicting someone's response to a situation - certain, probable, random, and...? OK it's token predicting. Instead it could be another kind of pattern. We don't use tokens, but we either use <some representation of information> or we ... don't?

What's the most significant, strongmanned, core difference that makes silicon doing number crunching "nothing more" and brains "something more"?
