That's because the DC Universe won't be the real world. The technology should be more advanced to fit the world. It's the same thing with Iron Man over at Marvel Studios. The world is still relatively low-tech like you said, and yet Stark is able to create all sorts of gadgetry. Same with S.H.I.E.L.D., who tapped into a cosmic energy source and generated a portal with their technology.
