A Dyson Sphere could power AI to reconstruct your digital self—even centuries after your death.
Key Takeaways:
- A Dyson Sphere could provide the energy needed to bring back humans through AI-driven digital resurrection.
- Russian transhumanist Alexey Turchin’s “Plan C” suggests that AI could rebuild people from recorded data.
- The concept faces major challenges, including human psychology, engineering feasibility, and data completeness.
- Experts debate whether a reconstructed digital self would truly be the original person.
- Even with a Dyson Sphere, achieving true immortality remains limited by physics and entropy.

The Vision: Digital Immortality Through AI and Megastructures
Imagine a future where humans are resurrected—not through mysticism, but through advanced artificial intelligence powered by a Dyson Sphere. This idea, proposed by Russian transhumanist Alexey Turchin, suggests that AI could collect historical and personal data, reconstruct people digitally, and even restore them biologically using DNA.
Turchin, a member of the Russian Transhumanist Movement, has spent years developing an “Immortality Roadmap.” His Plan C involves recording every aspect of human life—dreams, conversations, and daily experiences—to help AI recreate individuals in a simulated reality. Once a person has relived their life in this simulation, they could enter a digital afterlife, akin to Black Mirror’s “San Junipero.”
To power such an ambitious project, Turchin envisions a Dyson Sphere—an enormous solar energy-collecting megastructure first proposed by physicist Freeman Dyson in 1960. A network of orbiting satellites could harvest the sun’s energy, providing the computational power necessary for large-scale digital resurrection.

The Challenges: Feasibility, Identity, and Ethics
While conceptually fascinating, this vision faces major obstacles. Building a Dyson Sphere is currently beyond human capability, though Turchin believes nanorobots could one day mine planets for resources and construct it. But even with infinite energy, some scientists argue that AI cannot perfectly recreate a human being.
Stephen Holler, a physics professor at Fordham University, doubts whether enough historical data exists to replicate a person’s exact developmental conditions. Small, undocumented experiences shape personalities, making perfect digital resurrection unlikely. Instead, the AI would likely create a digital twin—a close replica, but not the same individual.
Clemson University professor Kelly Smith raises further concerns: even if technology advances, would humanity commit to building a Dyson Sphere, a project requiring centuries of work with no immediate benefit? Additionally, entropy and stellar evolution mean that no power source lasts forever.
Turchin acknowledges these challenges but argues that if a digital copy is indistinguishable from the original, it may as well be the same person. Whether this represents true immortality or a sophisticated illusion remains an open philosophical debate.
