Meta's Muse AI Agent Raises Privacy Concerns Amidst User Hesitation

Despite Meta's assurances and the hiring of Signal's Marlohn Spike to build its AI agent 'Muse,' users like David A. Mills express discomfort with granting Meta access to their personal information. The AI's functionality, while noted as "shockingly useful" by some, raises concerns about data harvesting and future ad-based monetization, echoing past privacy issues with Meta products.

“I do not know if this makes me a bad tech journalist, and it probably does. But I do not feel comfortable with Meta having my information, so I have not used it yet.”
“There are a lot of promises around Meta's privacy and end-to-end encryption with the virtual machine. And they hired Marlohn Spike from Signal to build it. And Mark Zuckerberg keeps saying his name like a talisman. You know? And in interviews like, well, Moxy Spike is here, nothing can possibly go wrong.”
“But the privacy problem from Meta is super real. And it feels to me anyway, like it hangs like a dark cloud over Muse. Like why would you give this company even more of your data?”
