Yes, the days of loser snake oil are over.
Just like the days of paper fiat currency backed by a gun is over.

Its just not dead yet.
And the new methods haven't laid many paths yet.

I learned to draw because I could never in a million years describe the things in my mind.
Even with drawings, it is still not enough some times.

And, I really dislike salesman like people.  So, please understand if I put all that in a box of don't go there.
It is the same with HR.  I won't form a company in The USSA because I would need to have an HR department.  I hate everything about HR.  Even the people that are attracted to those positions.
