There is a large elephant in the room that was barely touched on in the article: gravity. How does QM relate to gravity? Wikipedia puts it thusly[1]:

   Gravity has yet to be successfully included
   in a theory of everything. ... Theoretical
   physicists have not yet formulated a widely
   accepted, consistent theory that combines
   general relativity and quantum mechanics.
   The incompatibility of the two theories
   remains an outstanding problem in the field
   of physics.

The best attempt that I've seen so far is from a slashdot[2] discussion:

   Your momma so fat even if I'd entangle
   with her no information would be able
   to leave her event horizon.

      Nobody has managed to put gravitation
      and QM together yet, and you want to
      do it in a your-momma-so-fat-joke? Wow.
