This comment is like saying to somebody explaining the increased rate of car crashes with people talking on phones as a consequence of divided attention as saying that has nothing to do with that and it's because we're genetically conditioned to only focus our conscious attention on one task.

Mechanics and second order effects matter. Reductionism is a useful conceptual tool but it isn't a good representation of wider reality because things are more than the sum of their parts.

You seem to be missing the fact that genetics are simply encoding the proteins and it is the biological feedback systems mediated by dopamine that are actually driving our actions.
