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.
