The idea is to decouple the journals from the review step. They’ll still exist, but they’ll need to add other value. They’ll highlight, curate, add new perspectives. If they do a good job they can still be prestigious (like Scientific American or Wired). You’ll be proud that your reviewed preprint was highlighted by Nature, just like you’re proud when your paper is highlighted by the New York Times. You'll add that to your C.V. You'll still read them because they'll have good content.
