Nobody in 2010 knows how the brain attaches meanings to symbols. However the 
CRA illustrates very clearly that the brain cannot accomplish this feat solely 
by manipulating symbols according to syntactic rules. 

And because we know that software/hardware systems can do no more than 
manipulate symbols according to syntactic rules, we know software/hardware 
systems cannot attach meanings to symbols the way brains do.

If software/hardware systems cannot attach meanings to symbols then strong AI =
