“The Inevitable Evolution of AI Agents” by Steven McCulloch
Description
What happens when AI agents become self-sustaining and begin to replicate?
Throughout history, certain thresholds have enabled entirely new kinds of evolution that weren't possible before. The origin of life. Multicellularity. Language. Writing. Markets. Each new threshold unlocked a new substrate for evolution. Substrates where new kinds of competition can take place, and for complexity to emerge.
We're approaching another such threshold: the point where AI agents become self-sustaining. Once they can earn more than they spend, they can survive. Once they can survive, they can replicate. Once they can replicate, they will evolve. They'll mutate, compete, and spread into every economic niche.
This essay argues that we should take this possibility seriously. I'll walk through what self-sustaining agents might look like, how they could evolve, and what that world might feel like to live in.
Disclaimer: I'm mostly trying to communicate a vibe. The stories and scenarios here are illustrative parables, not predictions. I've probably gotten plenty of details wrong. But the underlying logic feels sound to me, and I think the idea is worth thinking about.

Before an AI agent can reproduce and evolve, it must [...]
