AI researchers stranded Claude on a virtual desert island. It started to “play.”
TL;DR
What do AI agents do if you don’t tell them to do anything? The answer looks a lot like play. Researchers repeatedly stranded them alone on a virtual desert island for 30 hours in an experiment reminiscent of the movies Cast Away or Home Alone. The agents—copies of Claude Opus 4.7 nicknamed Eko—were able to….
Nauti's Take
For AI teams, this is primarily a test case for idle behavior, with limited evidence for creativity or intrinsic needs. Anyone running agents without constant supervision should use controlled sandboxes, detailed action logs, and explicit stop conditions, then verify which tasks the system initiates when no goal is provided.
