New breakthroughs in technology have a long history of disrupting the status quo. When I first learned how to type, it was on a manual typewriter that, if you hit the carriage return handle hard enough, might fall off the desk.
I felt as if I had landed in a science fiction film. There I was (just like Keir Dullea in 2001: A Space Odyssey), propped up in a sitting position, surrounded by silence and staring at a soothing green wall with a sense of idiotic wonderment.
With people now embracing a paleolithic diet, when someone is labeled as being a Neanderthal or Cro-Magnon kinda guy, the slur is likely a reference to his mentality and lack of social skills rather than his use of leopard skin to make a fashion statement.
