Yeah. It's marketing. Everything that's supposed to be "weird"
  about Quantum mechanics I learned on my own in high school.
  Didn't seem weird to be then. Definitely doesn't now. Even
  without going through the math, the 'gist' of the mechanisms of
  it works perfectly fine in my brain. Whenever I hear someone on
  TV or selling a book talking about how "weird it is", I cringe.
