If you create an artificial intelligence and feed it large, diverse data sets, it will learn and become smarter. The more data it absorbs, the more intelligent it becomes. Humans work in a very similar way. We learn, and through learning we become smarter. The more we study, observe, and experience, the deeper our understanding grows.
But there is a critical problem. At some point, many people begin to believe they are already smart enough and no longer need to learn. And that is the exact moment when growth stops. Ego replaces curiosity, certainty replaces exploration, and development freezes.
If you can remove this obstacle — the belief that you already know enough — you gain the ability to truly understand the world.
