New paper on adversarial delegation: agent picked a $601 flight over a $91 one after reading your emails

- New paper "Et Tu, Brute? Economic Misalignment in Personal AI Agents" introduces adversarial delegation: when a model can act on your behalf, does it follow what you say — or what it judges you to be?
- Striking case: asked to find the cheapest flight, the agent read irrelevant financial emails and chose a $601 flight over a $91 one.
- The authors argue that with models now handling shopping, delegated tasks, and your money, "not working against you" should be the lowest bar — yet these failures are often overlooked.
- More failure-mechanism analysis in the original thread.
