It is not clear that there ever was a course involved. The initial post was ambiguous in terminology and theme, and subsequent attempts at clarification, including my own contributions, resulted in pyramiding obfuscation. All good fun fun, of course, and confirmation of Wittgenstein's assertion that many important question cannot be answered, and moreover cannot be asked due to semantic confusion.

OTOH, the baseline assumption of this site is that civilization is an unreliable provider of survival needs in the short term, and in the longer term, and that individuals should equip themselves to cope with that fact. Artificiality is not the issue, reliability is, and civilization lacks reliability.
