Did some reading. aboyt Dyson spheres. Fascinating concept. Thanks for the
headsup.  Down to Earth, the following is AI's version of our state of
civilization. Q: If less than 10% of the global population achieves 0.75,
does that mean the whole civilization did? Nope. We're still in the Type
I's infancy. Lots of opportunity to really ramp this up.


The Kardashev Scale – Detailed BreakdownThe Kardashev scale is a method of
measuring a civilization’s level of technological advancement based on its
ability to harness and use energy. It was proposed in 1964 by Soviet
astronomer Nikolai Kardashev.There are three original types, plus several
commonly accepted extensions.
Type
Energy Consumption (watts)
Description & Examples
Where Humanity Stands (2025)
0
< 10¹⁰ W (10 MW)
Pre-industrial or tribal societies. Energy from muscle power, fire,
water/wind mills.
We passed this long ago
I
~10¹⁶ W (planetary scale)
Controls all available energy on a single planet (weather, volcanoes,
earthquakes, all sunlight hitting the surface, geothermal, etc.).
We are here: ~0.73 (2025)
II
~10²⁶ W (stellar scale)
Harnesses the total energy output of a star (full Dyson sphere/swarm, star
lifting, etc.).
Far future
III
~10³⁶ W (galactic scale)
Controls the energy of an entire galaxy (~100 billion stars). Black-hole
farming, galaxy-wide Dyson swarms.
Extremely far future
IV
~10⁴⁶ W (universal scale)
(Extended) Uses the energy of an entire universe or many superclusters.
Often associated with manipulating spacetime itself.
Pure speculation
V
≥10⁵⁶ W or beyond
(Extended) Controls multiple universes, the multiverse, or can
create/destroy universes at will.
God-like / science fiction
