Yes. There is no reason to believe that we are any smarter than our ancestors. If one compares the wisdom of the Ancients to culture today, we may in fact have become significantly dumber. Technology is knowledge based, which accumulates with time; wisdom has to be re-acquired in every generation, and lately we have been flunking big time.
Our culture can afford to be so stupid because it is fantastically rich: older cultures showing such stupidity would quickly be wiped out by nature or less stupid neighbors.
