Definition
Growth Modes refer to distinct epochs in human history characterized by specific rates of economic and technological productivity growth. The “Big History” perspective (Hanson, Bostrom) identifies a sequence where each mode is significantly faster than its predecessor, suggesting a potential future transition to an even more rapid regime driven by machine intelligence.
Why It Matters
It provides a macro-scale framework for understanding the accelerating pace of human progress, from foraging to the silicon age. Recognizing these phase shifts helps us contextualize current technological disruptions within the multi-billion-year trajectory of complexity.
Core Concepts
- Historical Transitions:
- Hunter-Gatherer: Doubling time of years.
- Agricultural: Doubling time of years.
- Industrial: Doubling time of years (mixed mode currently).
- The Intelligence Explosion Precedent: If another transition occurs comparable in magnitude to the Agricultural or Industrial revolutions, the doubling time could shorten to mere weeks.
- Acceleration of Growth: Productive capacity that took 200 years to grow 7,000 years ago now takes roughly 90 minutes.
- Economic Doubling: Current growth rates () would make the world 34 times richer by 2100, but a new growth mode would dwarf this through “Intelligence Explosion” dynamics.
- How to read: “The rate of four percent.”
- Meaning: At 4% compound annual growth over ~75 years, output multiplies roughly 34× — but a new growth mode with weekly doubling would far exceed this.
