No I'm not saying they must work the same way. I'm saying it's evidence there is a more efficient way as they both solve the same problem and one is more efficient (in truth both are more efficient in different areas). At an abstract level they can be doing the same thing. What does a simulator do?

Think a little further yes, currently it's a brand new model each time but why will it be this way forever? Its an engineering problem one that we can solve and the brain is evidence it can be done.

Neural networks were originally inspired by the brain. Yes, they've deviated but there's absolutely no reason they can't take further inspiration.
