167 - Eliezer is Wrong. We’re NOT Going to Die with Robin Hanson

Grabby Aliens

Robin Hanson presents the intriguing "Grabby Aliens" theory, suggesting that alien civilizations are actively expanding across the universe. He argues that the universe is rapidly filling with these civilizations, which appear roughly once per million galaxies 1. This theory challenges the notion that humans are alone, proposing instead that we are early in the cosmic timeline due to a looming deadline where all available space will be occupied by these aliens 2.

The universe is right now filling up with aliens taking over everything they can. Soon, in, say, a billion years or so, it'll all be full and all taken.

Hanson's model suggests that these civilizations expand at a significant fraction of the speed of light, making them difficult to detect until they are upon us.

   

Alien Comparison

Hanson draws parallels between the evolution of AI and the spread of alien civilizations, highlighting the potential for both to diverge significantly from human values. He suggests that just as alien civilizations might spread like cancer, AI could evolve rapidly, leading to descendants with values vastly different from ours 3. This comparison underscores the unpredictability of future developments in both AI and extraterrestrial life.

Life on a planet reaching advanced level that it could expand in the universe is mathematically exactly like cancer.

Hanson's analogy emphasizes the potential for rapid and widespread change, whether through AI or alien expansion, challenging us to consider how we might adapt to such scenarios 4.
