The Kardashev Scale
Soviet astronomer Nikolai Kardashev’s 1964 classification of civilizations by energy command—extended by Michio Kaku into a framework in which the AI transition is not a technological event but a planetary-scale change in how much thinking a civilization can afford to do.
Nikolai Kardashev proposed in 1964 that extraterrestrial civilizations could be classified by their command of energy: a Type I civilization harnesses the full power of its planet, a Type II the full output of its star, a Type III the energy of an entire galaxy. Michio Kaku extended this framework into a general theory of civilizational development and then turned it on artificial intelligence with a precision that makes it one of the most illuminating instruments in the [YOU] on AI cycle. The insight is simple and vertiginous: energy and information are entangled. Every computation costs energy. Every increase in the intelligence a civilization can sustain—biological or artificial—is paid for in power consumed. A civilization’s command of energy is therefore also a ceiling on how much thinking it can afford. The hunger of large language models for electricity—training at the scale of cities, trending toward nations—is not an inconvenient side effect of
