A real physical device is much more complex, that is to say has many
more attributes, than any of our algorithms. So if you
have a simple thing and a complex thing you tell me which is making a
simplified approximation of which.

You could say that a real circle is only an approximation/
simplification of a real physical circle, which is made of ink
molecules, etc.
