That's what I'm saying.

But you can ask something to a recording. (Please stay on the line, your call is important to us... For technical support please say the name of the product or press one...) If I ask a ventriloquist dummy a question I will get an answer that would be the same as a real person too. The computation is nothing but recordings strung together with a lot of IF > THEN logic to synchronize the output with the input. It's correlation, not causation. The computations aren't understanding any questions or answers, they are just matching pre-selected criteria against an a- signifying database.

I don't think it has to be magical personally, but it definitely makes us different than a machine based solely on physical function.
