Super fidelity requires constant investment and discipline, but great companies know how to do that.

We learn more about how human brains work. And that leads us to ideas about how to make human brains work better.

Wayne Gretzky's talent doesn't come from studying everything he's experienced in hockey and making long-term game plans. It comes from constantly taking in all the data that's happening in the moment on the ice, and instantly generating constant predictions based on super-efficient mental models he's built in his head. Technology has to work more like Gretzky.

Fidelity is the total quality of an experience, including a sense of exclusiveness and aura. Convenience is simply how easy something is to get, which often means a low price and ubiquitousness. A super-fidelity product or service would lose its luster and quality if it's pushed too hard toward convenience. A super-convenient product or service would start to get expensive and exclusive if it moved toward higher fidelity, which would naturally undermine its convenience.

Who "wins" and who "loses" depends on when you measure it.

When someone is in a state of flow, that person's brain is not thinking about anything - it's just processing things through chunks at a total instinct level. Athletes in a state of flow describe knowing what will happen just before it does - knowing how a defender will react to a certain move an instant before doing it. Of course, if you know what will happen, you can succeed at doing it, so an athlete in flow has a stand-out game.

Some people seem to have extreme natural wiring - a talent that seems to come out of nowhere. Like a music savant or prodigy. The uplifting news, though, is that many talented people don't have such natural wiring - but they forge a talent through thousands of hours of what's known as deliberate practice or deliberate performance.
