Type II

A Type II or K2 civilization has control over their solar system, and may be able to harness the power equivalent of a single star. It extracts fusion energy, information, and raw-materials from multiple solar systems; it is capable of evolutionary intervention, interstellar travel, interstellar communication, stellar engineering, terraforming, and star cluster-scale influence; the resulting proliferation and diversification may negate the probability of extinction. Complete control of the fate of its home planet where threats like ice ages and global warming can be avoided.

A utopian outcome would be a hybrid galactic culture, with millions of cooperating worlds in a galactic community. Poetically, this would be a mammoth archipelago of solar system societies, a multitude of civilized islands separated by the vastness of the oceans of space.

A dystopian path is also possible. Aggressive and ruthless expansion could lead to an uncontrolled sprawl far beyond any form of functional government, regressing into societal collapse and eventually a form of interstellar barbarism with little regard for life.
