This elitist attitude, is another mainstay of the Erlang community that hasn't helped in the slightest. What is the reason it's not popular again? My reasoning is not "a bad take", as much as it's my take from over 30 years programming. I would say it's my own twist on common understandings across the west coast of the US. You probably have your own, equally wrong reasoning. Would be great to hear them.
