Everybody has only a 24-hour day. Most people, if they increase consumption of one medium (like magazines or books) will cut down on another (like TV). This drastically reduces the sort of growth some people have been expecting.

Computers are hierarchical. We have a desktop and hierarchical files which have to mean everything.

History is fractal. The closer you look, the more complicated, yet always repeating patterns.

We live in media, as fish live in water.

They were saying computers deal with numbers. This was absolutely nonsense. Computers deal with arbitrary information of any kind.

Everything is deeply intertwingled.

Making things easy is hard.
