If we get the cool sort of aligned ASI that gives us effectively infinite intelligence to build and create at scale, we will likely end up building black holes and harnessing them for energy, manufacturing, and quantum simulations.
For a spinning (Kerr) black hole, efficiencies reach ~10–42% of the infalling rest-mass energy converted to usable radiation - far surpassing nuclear fusion (~0.7%) or even antimatter annihilation in practicality for bulk use.
Quasars demonstrate this on galactic scales. A civilization could feed asteroids, waste, or dedicated fuel into a disk around a stellar-mass or mini black hole and harvest the output with collectors or Dyson-like structures. Spheres around stars are child’s play versus gravitational singularity industry.
I’m generally opposed to over-regulation, but we’d want to be very careful where we build these and who is in charge of them 🤣.
