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.

In the long run magazines can't be a convenience play - the Web has stolen that. So magazines have to be high fidelity - a fantastic experience - to thrive. Magazines will survive the Internet age, but only the ones that give people an experience they just can't get anywhere else. A magazine will have to be truly loved to make it.

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

Artificial intelligence uses a complex set of rules - algorithms - to get to a conclusion. A computer has to calculate its way through all those rules, and that takes a lot of processing. So AI works best when a small computer is using it on a small problem - your car's anti-lock brakes are based on AI. Or you need to use a giant computer on a big problem - like IBM using a room-size machine to compete against humans on Jeopardy in 2011.

Our brains are great at knowing what to forget. We actually have to teach computers to do the same.
