One-off cost decline is not Scale. Cost decline that goes on for a decade or several decades is Scale, something that you can build an entire economy on. Free Radicals find things that Scale year in and year out. The other way to think about Scale is in terms of numbers. Is the market for what you’re doing a thousand people? Ten thousand? That’s okay, but not Scale-worthy. A Free Radical should ask—can it be used by a million people? Ten million? A billion? Now that’s something that Scales. This is the question I ask every time I look at a new product, a start-up, or a new industry. I instantly lose my baked-in biases of what something costs today, or what it can do today for a given cost of, say, $500, and just mentally slide down the cost curve.
