The over-all point is that new technology will not necessarily replace old technology, but it will date it. By definition. Eventually, it will replace it.

I feed on other people's creativity, photographers, artists of every kind. Sometimes a feeling that you get listening to a song can be so powerful.

It is the supreme art of the teacher to awaken joy in creative expression and knowledge.
