With apologies to Humphrey Bogart (Treasures of the Sierra Madre), I want to get you all to think and discuss the long historical argument as to whether we really can have randomness in cryptography.  Some argue that RNG can be truly random while others state there is no such a thing in the science.  For the most part our reading brings us to the conclusion that PRNG is good enough.  QUESTION: Is Randomness a reality or a pipe dream?
BTW:  Funny story in that when Apple introduced the IPod, they had the random feature programmed to be random as you would expect.  But, users hated it because they would get the same song replayed immediately after it was played (real randomness would do this, right?).  So, Apple had to go into the software and reprogram it so it was no longer random but actually pseudo-random to ensure that once a song was played it was not played again until the rest of the songs were played in a random method.
