The surest thing we know of our future, is that most of our predictions will be wrong, and will seem silly in the light of the actual events. Humanity has a remarkable ability to make it up as we go along. What will the weather be like tomorrow ? I'll tell you tomorrow.
You don't need a weatherman, to tell the way the wind's blowin'.

Some predictions will be right, but we will have to listen for the music through gunfire. How do you get yourself heard against a marching band ? Wave a red flag.
