Alternative Scenarios
Stagnation or Collapse: Civilization could plateau at Type 0 or regress due to resource depletion, societal collapse, or self-inflicted catastrophes. The “Great Filter” hypothesis suggests many civilizations fail to progress beyond a certain point.
Non-Kardashev Pathways: The scale assumes energy consumption as the primary metric of advancement. Future civilizations might prioritize information processing, consciousness exploration, or minimalism over energy expansion, rendering the scale less relevant.
Transcendence: Humanity might abandon physical expansion for virtual realities or merge with a cosmic consciousness, bypassing traditional Kardashev milestones.
