Medium-Term Future (500–1,000 Years): Toward Type II
Energy Harnessing: A Type II civilization would require capturing the full energy output of the Sun, possibly through:
Dyson Swarm/Sphere: Constructing a network of solar satellites or megastructures to encircle the Sun and harvest its energy. Early steps might include orbital solar farms or space-based solar power stations.
Interstellar Expansion: Colonizing nearby star systems to access additional resources and energy sources, enabled by breakthroughs in propulsion (e.g., antimatter drives, laser propulsion, or speculative warp drives).
