Writing = thoughts put on paper. When writing was a "specialist" activity it was due mostly to technical difficulties rather than people needing a whole new breed of skills. The anatomist analogy is a good one. But if we extend it to IT, it doesn't mean everybody should be able to program. Rather, everybody should know basic computer operation and how to use the most popular programs.
