Man vs. Machine...Who is using who?

   The web is an always changing medium, that in a way makes us think not differently, but more efficiently because there is always room for revision.  We now write shorter, more elusively and informally because the internet is really just a giant blog.  Many believe that the computer's capabilities will soon trump those of the human brain.  However, we must ask ourselves, who is behind the computer?  A human.  This reminds me of the Wizard of Oz, where Dorothy discovers that there is not really an all knowing wizard, but just the man behind a curtain.  Isn't that really all the internet is?  We feed it so much information about ourselves such as the music we listen to, movies we want to see, fonts we use and social networking accounts.  So in reality, we are the "man behind the curtain", we are the machine.  Welsh argues that the machine can be using us, however we are the machine.
