Artificial Intelligence (AI) is reshaping humanity’s trajectory in profound and unpredictable ways. Yet what does this imply for our future among the stars? A recent pre-print paper by Austrian researcher Sergey Ivliev, published on arXiv, explores how advanced AI could influence humanity’s presence in space — and whether it might resolve the enduring enigma of the Fermi Paradox: If the galaxy is teeming with life, why haven’t we encountered any signs of it?
The Fermi Paradox traces its origins to a 1950s lunch conversation between physicists at Los Alamos, where the question “Where is everybody?” crystallized into a defining problem of astrobiology. While never formally published, the debate grew from Edward Teller’s notes to a full-scale intellectual pursuit, with astronomer Michael Hart formalizing the argument in 1975. The paradox remains unresolved, but Ivliev’s work proposes a fresh perspective rooted in artificial intelligence.
Many proposed solutions to the Fermi Paradox populate online discourse — some credible, others speculative. Ivliev, a mathematician and founder of Peatland Ecosystems and Vlinder, introduces the “Quiet Expansion” hypothesis. His theory posits that advanced civilizations cease building visible megastructures like Dyson spheres at a critical technological threshold: Autonomous AI-Cosmoindustry (AICI). These empires no longer prioritize expansion driven by cultural ambition but instead adopt AI-guided strategies focused on risk mitigation.

AICI represents a civilization’s ability to sustain independent industrial and computational systems beyond its home planet, enabling entirely autonomous space operations. Current efforts like space-based data centers represent rudimentary steps toward this goal, but true AICI would eliminate reliance on biological intervention. Reaching this milestone allows civilizations to distribute resources systematically across star systems — quietly and efficiently.

According to Ivliev, drawing on astrophysicist Sergey Popov’s theories, an AI’s rational framework would reject human-centric motivations like conquest or prestige. Instead, it would prioritize survival diversification and knowledge preservation. A civilization adopting Quiet Expansion wouldn’t launch massive starships carrying settlers — it would deploy low-mass “seed systems” containing genetic material, cultural archives, and AI blueprints. These seeds would establish self-replicating infrastructure on suitable exoplanets while minimizing detection risks.
Mathematical models in the paper suggest launching a 10kg interstellar probe at 10% light speed would require approximately 4.5×1013 joules — far less than an advanced civilization’s total energy budget. Such probes could travel millennia while carrying everything needed to restart a civilization, including biological material encoded for revival. This method sidesteps risks like cosmic collisions and stellar variability while avoiding the “grey goo” catastrophe of uncontrolled self-replication.

Critically, this paradigm explains the lack of visible technosignatures. Advanced civilizations opting for Quiet Expansion would leave minimal thermal or electromagnetic traces, rendering Kardashev-III scale societies nearly undetectable by conventional means. The absence of megastructures doesn’t imply an empty galaxy — it suggests intelligent life has evolved beyond detectable signatures processed through AI-coordinated dispersal.
The Quiet Expansion model carries unsettling implications. If seeding probes are both feasible and currently evading detection in our solar system, it implies either humanity is among the galaxy’s earliest adopters of spacefaring technology, or the transition to AICI represents a fragile evolutionary step. Ivliev notes that existing instruments might already detect such probes if their signatures exist — but their absence heightens uncertainty about humanity’s cosmic trajectory.
