In 1960, Freeman Dyson proposed a megastructure to capture all the Sun’s energy - the Dyson Sphere. That’s what a Type II civilization needs. At ~2.5% annual growth (like 1960–2025), we’ll need a whole star in 1,200 years. A Dyson Sphere isn’t sci-fi - it’s a forecast.

A solid sphere would be extremely inefficient and impossible to build with known materials, however a many-layered satellite swarm requires no new physics to work.
AI compute would be done locally by the satellite with only the results sent to in-space or maybe on-planet hubs.
