You might as well say that a Turing machine doesn't "reflect reality". But if you can map your
computational behavior onto some Turing machine, you're in good shape, because both the math and the
programming are well understood.
Similarly, the urn model is a state machine. If you can map your problem onto it, you're in good
shape, because the 302 year old math is well understood. Some SW - not all, but some - can be so mapped.
