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.

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

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.

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.

A CD these days is not all that convenient, and it doesn't bring enough fidelity to make you put up with that inconvenience. So, nobody buys CDs anymore.

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

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