However, it's kind of exciting (from a nerd point of view) to be alive in a time with so much innovation (mind you, it could be argued that being alive at anytime in history would satisfy this criteria, except for the dark ages of course.) Check out one application of quantum theory that will ensure the quantum memory in my quantum computer in the year 2050 won't get away with spontaneously switching a 1 to a 0 (i.e. memory error correction). ... and no, they haven't figured out how to construct Scotty's transporter...yet. Damned Heisenberg compensators!
