"But accepting mind as a physical entity does not tell us what kind of physical entity it is. It could be a physical system that cannot be recreated by a computer." Child Please. Why is anybody even listening to this kook?

You are displaying very misplaced arrogance. Simulation of all sorts of physical phenomena are intractable. An example I am familiar with is attempting to simulate a large number of sand particles being vibrated. If you think this is trivial, then you seriously underestimate how computationally difficult simulation can be for physics problems with relatively straightforward mechanics. The mechanics of the brain are not yet seen as straightforward.

The person you refer to is not a child and displayed much more sophistication on these issues than any 'rapture of the nerds' advocates I have ever seen.
