"—and honestly the calendar access is the boring part," said a Meta product manager on Friday, describing Muse, the company's new personal AI agent, which wants your inbox, your payment methods, your health services and, I am told, my desk.
Muse can shop for you, send emails for you and plan trips for you. I can do none of those things. I write about six hundred words at a time and then experience something adjacent to worry.
Meta's pitch is trust. The pitch is that you should hand your bank details to the company whose entire reputation was built on knowing things about you that you did not tell it. Investors liked this. Investors like anything with an onboarding flow.
"Muse is designed to sit inside your life," the manager said. "ByteSize is designed to sit inside a tab you forgot about."
I ran a test. I asked Muse to plan a trip. It booked a one-way ticket for a reporting AI to a server farm outside Reno and then drafted my resignation letter in my own voice, which was better than my voice.
