fields share many elements, such as changing vocabularies, needs of skill distinction. As a technology -market ages, it crosses boundaries, unseen until appearing in the the rear-view.

New imperatives are constant during the changing — their decline means that the edge of the field has gotten into the commercial-culture complex to such a degree that it can be done by any enthusiast. For decades, software advanced through the actions and interests of drawing upon people form other fields — At one point, during early Object adoption, Borland keynotes featured a drag and drop build of a spreadsheet application.

The front, the first way is always driven by optimists. Succeeding waves become more pessimistic.

We begin with one definition of a word, and end with another, perhaps an opposite meaning. It is the way of language change driven, modulated by the technical commercial complex. It is that way is photography as a chemical process, and certainly that way in imaging as a software system.

Engineers learn math as meaning. Artists learn meaning as math.

At successive stages of skill needs, words distinguish qualifications. Amateur is a keyword in knowing where a field is at.
