To really understand a concept, you have to “invent” it yourself in some capacity. Understanding doesn’t come from passive content consumption. It is always self-built. It is an active, high-agency, self-directed process of creating and debugging your own mental models.
— François Chollet (via Simon Willison)
It’s a rephrasing of our “The best way to understand something is to teach it to someone else”. And that’s why I still love my job.
