Optimism has powered every major breakthrough in history, from the first airplanes to the eradication of deadly diseases. Even as the world faces climate change and inequality, a belief in improvement remains crucial. Progress is often invisible because it happens slowly and rarely makes headlines, but societies that generate even a small surplus of good see those gains compound over centuries. Trust in future generations and the willingness to tackle new problems ensure that humanity continues to advance.
