< Anyway, the metaphysical commitments seep in at Church-Turing, I think. It's 
easy to lob accusations at, say, Roger Penrose for making a speculative 
argument that humans may be able to do things computers can't do. But I see 
both sides as making *useful* metaphysical commitments. One side has faith that 
our current formal systems will eventually reason over biological structures 
like the brain as *well* as they can reason over artifacts like the 
Transformer. The other side has faith that biological structures lie outside 
the formal systems we currently have available.>

These seem to me to physical issues not metaphysical issues.   He's not 
proposing that humans *cannot* be understood, but that they may be 
insufficiently understood.
In any case, quantum chemistry can be simulated on classical computers.  So it 
is a question of degree not category.
