Yes, this is my argument. But understanding day to day things doesn't need atomic level details. For most things your measurement precision matches a model at a much higher level. You can stop at Newton's or Einstein's equations whenever that fit's your view of reality. People use that to extrapolate in the other direction, and assume that because Newton's laws can be simulated, you can simulate an atom, thus everything. We don't have a view of reality at subatomic levels that says: "this is it and there's nothing beyond it". You don't know if your simulation of a brain will show an emergent intelligence if simulated with 'float', 'double' or 'infinite'.
