A brain operates at the level of neurons, not individual atoms.
The vast majority of atoms in the brain are there to do non-cognitive things.
The tiny fraction actually doing neural things are insanely redundant.
You can simulate a 1 kg ball dropping from 100 meters, to time its collision with the Earth, by simulating all its atoms. But the net mass of the ball is what matters. Not the individual atom masses and movements.
Likewise, you can simulate a brain by simulating all its atoms. But the net movements of transmitters are what matter, not all those individual atomic movements.
Neurons and transistors both operate on net signals precisely so they can be insensitive to individual atomic behaviors. If they were sensitive to individual atoms, they would be noise generators instead of reliable information processors.
And because they are designed to be insensitive to individual atomic behaviors, we don't have to model them at the atomic level.
(Which is impossible anyway. The quantum field equations for even two interacting atoms are complex. There is no visible future in which the atoms of a single neuron could all be simulated accurately, much less a brain. Even then, because of quantum noise, the atomic model wouldn't be any more accurate.)
