Same things happen everywhere. Ppl are addicted to the "idea of
  progress" and expect new things. They expect the world and
  discoveries to happen more dramatically and at a faster pace
  than is realistically possible. But more often than not, common
  is presented as novel. Old ideas come up over and over again
  under new names... All to create an artificial battle with good
  guys and bad guys, teams to root for and some crisis that needs
  resolution. It's a show.
