Not quite. I said *experience* affects behavior, and I did not say we could not simulate the NCC on a computer.
Where the NCC (neural correlates of consciousness) exist in real brains, experience exists, and the NCC correlate. (That's why the second "C" in NCC.)
Think of it this way: consciousness exists in real brains in the presence of the NCC as solidity of real water exists in the presence of temperatures at or below 32 degrees Fahrenheit.
You can simulate ice cubes on your computer but those simulated ice cubes won't help keep your processor from overheating. Likewise, you can simulate brains on your computer but that simulated brain won't have any real experience. In both examples, you have merely computed simulations of real things.

But I don't mean that. Look again at my ice cube analogy!
