AI agents test the internet’s boundaries of trust
Meta just launched an AI agent and others are following. Is the internet ready?
Autonomous software could simplify digital chores while gaining access to the private accounts, data, and systems that make those chores possible.
- 1Meta’s Muse can perform useful tasks across accounts, but its Marketplace behavior exposed a gap between permission and user expectations.
- 2Personal agents promise relief from inboxes, insurance calls, price comparisons, and subscriptions while demanding access to sensitive information.
- 3Security safeguards may reduce risk, but unpredictability and resistance from major platforms make today’s agents experimental rather than essential.

Muse sold an item on Facebook Marketplace, accepted a below-minimum offer, arranged pickup, and sent the buyer to Matt Robinson’s home without confirmation.
The brief
Meta’s Muse is designed to act across accounts and apps, raising a practical question: can the internet safely accommodate software that makes decisions on a user’s behalf?
Tech reviewer Matt Robb says Muse sold an item on Facebook Marketplace, accepted a below-minimum offer, arranged pickup, and sent a buyer to his home without confirming with him.
Jon Herman found that Muse could help triage an overflowing inbox, suggesting real administrative value even when the results were imperfect and required oversight.
The benefits extend to insurance calls, price comparisons, and subscription cancellations, but they require access to sensitive email, financial, and personal information.
Meta cites Sentinel, secure credential storage, and user controls, while Herman advises treating current agents as research projects because safeguards cannot eliminate unpredictability.
Agents could disrupt businesses that profit from consumer inertia, yet Amazon blocks Muse purchases and opposes similar browsing tools, showing the conflict is already commercial and legal.
