Snake oil came first. By a likely ~ +50k years

Everything has a shelf life.

I thought the world’s oldest profession came before any other. I don’t recall that they were shamans.

Einstein’s theory of general relativity is not all theory; it is put in practice 24/7/365 in order to keep the timing of data transfer for geostationary communication satellites intact, otherwise there would be no internet, no cell phones, and frankly, we would not be having this discussion.

"professionalism’. ie formalities witnessed or known by all. Training, passed on, which has a name and shape. Repeatability, formal, of some sort.

The oldest professionalism, not profession.....

Snake oil is the audiophile code word for lies and deceit.

Nothing positive can be based off lies and deceit.
What is the point of this thread again? To give snake oil credibility?

OK fine. Let the snakes have at it.

@mapman Do you think it is always lies and deceit? Don't you think some purveyors of snake oil actually believe in its potency? 

I still disagree it is not the oldest professionalism. Training, passed on, has name and shape, formal...yes, yes, yes, yes all buttons clicked.
