As automation, AI, and new job models reconfigure the business world, lifelong learning has become accepted as an economic imperative. Eighty percent of CEOs now believe the need for new skills is their biggest business challenge. For employees, research now shows that opportunities for development have become the second most important factor in workplace happiness (after the nature of the work itself). At the most fundamental level, we are a neotenic species, born with an instinct to learn throughout our lives. So it makes sense that at work we are constantly looking for ways to do things better; indeed, the growth-mindset movement is based on this human need. And whereas recruitment is an expensive, zero-sum game (if company A gets the star, company B does not), learning is a rising tide that lifts all boats.
