Stefano, your argument is fine .... except that you have neglected to 
notice that I was talking about whether a PC could simulate a mind "in 
real time".  In other words, from the very beginning I have been talking 
about anything EXCEPT the universal computation issue!

I never disputed whether a tinkertoy or a bunch of marbles running in a 
maze (or a Searlean idiot locked up in a room with pieces of paper being 
passed under the door) could simulate a mind .... hey, no problem:  all 
of these things could simulate a mind if programmed correctly.

All I cared about was whether a PC could do it in real time.  In other 
words, fast enough to keep up with a human.

Does that clear up the confusion?
