Yes, but it's still possible to imagine what would happen *if* something were
done that at the moment seems impossible. If sodium chloride were produced
by a machine which causes the transmutation of hydrogen into other elements,
would it still taste salty? I would say that the answer is "of course", whether or
not such a machine could ever be built. I don't even see how it is *logically*
possible that pure NaCl could taste different depending on where it came from.
