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.

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.

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

High fidelity is a rich experience, and you'll put up with terrible convenience to get it - maybe it's high cost, waiting in line, jumping through hoops. High convenience is the opposite - it's a commodity, but it's cheap and easy and ubiquitous. A great exclusive boutique shop is high fidelity; Wal-Mart is high convenience. Both are hard to establish in their own way. The thing to remember about sustaining either is that you can't sit still. Some other entity will always find a way to challenge your fidelity position or your convenience position.

Our brains seem to have the power to do one or the other - record and remember every detail, or chunk it to higher level concepts and forget the details. We can't seem to do both. The fact that you could not fly over a city and remember every detail is not something to worry about.

The explosion of the Web and digital media from 1995 to 2000 shook companies more profoundly in a shorter time than anything since the end of World War II.
