What is John's reaction to the "civilization"? Why does he call it a "brave new world"?

John's attitude towards this "brave new world" changes as well. By visiting work sites and participating in the world’s social elements, John becomes increasingly disillusioned with his surroundings. Bernard notes that John often does not feel awe the technology around him, which he considers strange for someone from the reservation, which has no technology or science. John, however, holds onto something else: myth and story. Visiting this "new world" is a new experience for Savage; he finds it a new frontier, an "undiscovered country." The title is taken from Shakespeare's The Tempest,

 "Oh, wonder!  How many goodly creatures are there here!  How beauteous mankind is! O brave new world, That has such people in 't!"
