There are no radio signals coming from Type I, II, or III civilizations. If a civilization is a million years old, surely we should notice their presence. The fact of the matter is that Type 0 civilizations like ours might be quite common in the universe, but they destroy themselves before reaching Type I status because of the very fear and hatred I just mentioned. With this discovery comes a fork in the road. To the left is prosperity, to the right is destruction.
Chances are most civilizations veer to the right.
To choose the left requires a willingness to let go of national boundaries and idealistic dogma. There is no room for our fear and hatred on the journey up the Kardashev ladder. Will we take the easy way out, or will we choose the road less traveled. Our decision will make all the difference. The Kardashev system is beautiful in its simplicity, and in its rejection of future projections based on simple extrapolation of current technology.
