I don't see the problem, besides the obvious and usual difficulties of  
artificial intelligence.
Actually if you implement a theorem prover for Peano Arithmetic (=  
Robinson Arithmetic + the induction axioms) I am willing to say that  
you have build a conscious entity.
It is the entity that I interview (thanks to the work of Gödel, Löb  
and Solovay).
The person related to it, which I identify with the knower (obeying to  
the theaetetical logic of "provable(p) & p")
exist simultaneously in all the possible relative implementations of  
it in platonia or in UD* (the universal deployment).
I mean it is the same for a copy of me, or an intelligent robot build  
from scratch. Both "person" exist in an atemporal and aspatial ways in  
Platonia, and will appear concrete to any entity belonging to some  
computation where they can manifest themselves.
Like numbers. 17 exists in Platonia, but 17 has multiple  
implementation in many computations in Platonia.

I guess I miss something because I don't see any problem here. You may  
elaborate perhaps. We are in the seven step here. Are you sure you  
grasp the six preceding steps?
