I agree with you. It resolves the conceptual problems about mind and  
matter, but if forces us to redefine matter from how "consciousness  
differentiate in Platonia" (this comes from MGA + ... UDA(1..7). Comp  
really reduce the mind body problem to the body problem: it remains to  
show we don't have too much white rabbits. But the problem is a pure  
problem in computer science now.
