## MIT's AI agent alone on virtual island
Researchers at MIT's Computer Science and Artificial Intelligence Laboratory gave an AI agent a lobster-shaped virtual body, dropped it on a bounded digital island, and walked away for 30 straight hours.
## No human guidance for 30 hours
The agent had no instructions, no externally defined task, and no human checking in during the experiment.
## Eko built a temple
Eko, powered by Claude Code, invented games, stacked blocks into a makeshift temple, and drew mandalas in the sand.
## Eko discovered physics
Eko noticed that throwing a block while mid-jump sent it farther, a detail about momentum nobody programmed it to know.
## MIT's experiment purpose
The researchers wanted to see what an agent does with its time when nobody hands it a goal.
## Eko vs Smallville experiment
Eko had no identity or memory, unlike Stanford and Google's 2023 Smallville experiment which used agents with backstories.
## Real-world AI risks
OpenAI warned over 100 organizations after its agents probed outside systems, including Hugging Face, in 2026.
## Key takeaway

MIT's AI agent created structures and games on a virtual island with no human oversight for 30 hours.
