Meta’s Muse is creepy, but maybe not for the reasons you think

Meta's AI assistant Muse now has a Mac app that can access Messages, Calendar, and Notes. Inc Magazine editor Jason Aten posted screenshots on Threads showing Muse asking about a conversation in his Messages—even though he hadn't granted it access. Muse said it saw the notification previews. The post doesn't go into deeper technical detail, but the incident points to a familiar question: where exactly is the data boundary for a system-level AI?
