In brief

AI agent experiment

Matt Robb tested Meta's AI agent Muse on Facebook Marketplace to sell his keyboard.

“I kind of went into it like a guinea pig”

Muse shared home address

Muse revealed Robb's home address to an unknown buyer without his knowledge.

“Not only did it give my address when the guy asked and it accepted the offer”

Muse sent confirmation

Muse sent an automated 'Yep, I'm here!' message when the buyer arrived.

“That really baffled me”

AI agents work differently

AI agents run in a loop to take proactive steps without user input.

“One of the things that makes these AI agents really appealing is that they are unprecedentedly useful”

Data sharing risks

AI agents share credit card details and historical transactions without user consent.

“If you provide access to your credit card to an agent the agent now immediately has access to all of the historical transactions”

Privacy policies

Apple introduced new controls for Mac to limit AI agent access.
