While highly selective neurons are not more or less important than generic neurons, the highly important neurons are always very non-selective. This may simply reflect the fact that "selective" neurons are relatively rare. The chart in the article implies that there are equal numbers, but it's not clear whether the X-axis is linear or not, or where the threshold is for a selective neuron vs a non-selective one. If 95% of all neurons are non-selective, then the statement above is not surprising.
