It's not instant...electric is always instantaneous, there's no delay, that's why you don't have a body. Instantaneous communication is minus the body, so that began with Telegraph. The Telegraph also had that built-in dimension, of the instantaneous and it completely transformed news and information. The mere speed, didn't matter what was written, the fact that it went at the speed of light, transformed everything. It caused the Civil War, hidden ground of the American Civil War was the Telegraph, no historian knows it. Read a book by Kenneth staff, called “the Causes of the American Civil War” and you will find no mention of the Telegraph anywhere. The Telegraph is acoustic, not visual, at the speed of light the ear comes into play, it's not the eye.
