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 =
false.
