The Neo-Kardashev Scale: A Thermodynamic Framework for Regenerative Civilizations

Key Points

To redefine the concept of civilizational advancement by focusing on the capacity to enhance biological complexity instead of energy consumption.
Critique existing Kardashev Scale and its implications for sustainability.
Introduce the concept of the Neo-Kardashev Scale based on thermodynamic principles.
Define 'negentropic enhancement capacity' as a measure of progress.
Highlight the inadequacies of energy-focused metrics in defining progress.
Establish a foundation for assessing civilizations based on their ability to increase biological organization.
Suggest a shift in how civilizations should be evaluated to ensure long-term ecological sustainability.

Abstract

The Kardashev Scale (1964) measures civilisational advancement by energy consumption. While revolutionary for SETI research, this framework encodes an extractive paradigm that is thermodynamically incompatible with long-term survival — conflating energy throughput with progress while ignoring biosphere depletion. We propose the Neo-Kardashev Scale, which redefines civilisational advancement as negentropic enhancement capacity: the measurable ability to increase organised biological complexity rather than merely harness energy.
