You can and must understand computers now.

So in my uncertainty, I went to graduate school and there it all happened.

If computers are the wave of the future, displays are the surfboards.

So, the point was to be able to have a medium that would record all the connections and all the structures and all the thoughts that paper could not. Since the computer could hold any structure in any form, this was the way to go.

The ideas keep going, you have the material, you cut because there's a limit to the space allowed to you. And the space is limited because of some other constraints that have to do with money or printing or whatever.

The problem is not software 'friendliness'. It is conceptual clarity. A globe does not say, 'good morning'. It is simple and clear, not 'friendly'.

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