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

A user interface should be so simple that a beginner in an emergency can understand it within ten seconds.

I have long been alarmed by people's sheeplike acceptance of the term 'computer technology' - it sounds so objective and inexorable - when most computer technology is really a bunch of ideas turned into conventions and packages.

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.

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

The paperless office is possible, but not by imitating paper. Note that the horseless carriage did not work by imitating horses.

You can and must understand computers now.
