Re points (1) and (2): Ha, that sounds like bootstrapping would be necessary. > So my feeling is that, by all means, we should be teaching anyone and everyone how to code, to lay the groundwork for teaching computer science.

It depends on the context, especially regarding the language and associated libraries etcetera being used.
