Why would you expect that? Statisticians and scientists have to go to great lengths to get samples representative of the population at large, and I hardly think a business or industry is a proper random selection.

That may be because it was smothered in dumb memes and jokes.

I actually appreciate the humor, but I'm in the same boat where there's a good portion I'm just not wrapping my head around clearly. I'd love if someone made an annotated version with technical descriptions.
