In theory you could predict from calculation that lots of H2O molecules would form a liquid and even predict what its freezing and boiling point was, but in practice you could not because it would take far far too many calculations for even a super-computer to make; but you could do it if you had a quantum computer, those sort of machines would be especially good at performing quantum mechanical calculations and simulations. And that is why I think a quantum computer is one of two things that could produce a singularity, the other being Nanotechnology. > > In the latter case the emergent phenomena is something qualitatively new > and different than it’s reduced fundamental parts.
