Chunking makes our brains more efficient. The more you can chunk something, the faster and easier you can process it. Wayne Gretzky had chunked hockey like no one before or since. Talented people have supremely chunked whatever they become talented at doing.

If you spot a market where the only choices are at either one end or the other - high fidelity or high convenience - there's probably a big opportunity at the other end. That was the opening for Federal Express, for instance. When it started, there was only one mail service in America - the US Postal Service, which was high convenience. Fred Smith created a high-fidelity mail service.

I'm that tech writer who gets on stage and plays funny tech songs. I wouldn't want that to be all I'm known for, but it's a bit of a differentiator.

Babies have not yet chunked anything. They aren't doing any high level thinking. All they're doing is sucking in all the data they experience in the world around them, and remembering it, raw. It's basically what extreme savants have happen in their brains.

Anybody can develop a certain amount of talent at something. However, the supremely talented - the superstars - are people who have married a gift of brain wiring to those thousands of hours of practice, usually in favorable circumstances.

If you want to stand out, find a way to be either high fidelity or high convenience in whatever you do. If you're halfway in between on both measures, you're not going to make people feel very excited about you.

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