The Twentieth century gave the human race its score card. Kardashev and Dyson made concrete the notion of type one, type two, and type three civilizations.
A type one civilization has mastered its planet, inside out, is utilizing the world's entire energy potential, and has wiped away all the internal struggles of its race. A type two civilization has energy needs so massive that it can only be met by physically harnessing the sun. In the type three scenario, the civilization has gone galactic, extracting energy on an interstellar basis.
We can make magic with engines smaller than a virus, and yet, just today, twenty-four people in this city alone will die from having walked into the wrong district or community. We are still not even a type one civilization. This remains a zero society.
