Penrose's argument has always been full of it. Humans aren't Turing-complete; they can certainly emulate a small, finite, Turing machine, but they can't emulate an arbitrary large one. An individual human is not complete in any way; look at how many people have failed to proof Fermat's last theorem. Finally, people aren't consistent; Robert Penrose can say "Penrose will never utter this statement" and the roof doesn't fall in.
