Even according to platonism souls are forms and forms are described by science. The only difference is that forms are substance and can exist detached from matter, but this doesn't affect computability. Moreover, mathematics is epitome of eidos.
The commenter's point was to disagree with the previous comment that "souls aren't real". Lack of evidence either way means we don't know. Occam's razor, while a good heuristic, is a heuristic, not a theorem.
