According to Osho, the slide from Satya Yuga to Kali Yuga mirrors a person’s journey from innocent childhood to jaded old age: society loses guilelessness and non-division, and accumulative cleverness, calculation, and dishonesty ascend. Intellect dethrones the heart—poetry yields to numbers—so outer progress grows while inner bliss withers. Hence it’s decline, not development; true measure is preserved joy, not machines, data, or reach.
Humanity got smarter and busier but lost its childlike heart and happiness, so real progress means choosing joy over cleverness and stuff.
