> There is no need to approximate a ReLu or tanh well
Similarily there might not a need to emulate neurons well to get the circuits in the brain to work. However when someone makes arguments that neurons are equivalent x artifical neurons it is necessary to choose a bound for comparison (fe. L2 error of activation) for the emulations you compare.
