Meta's Muse tops the App Store — but whose interests does your AI butler serve?

Exponential View (Azeem Azhar) · rss · 2026-09-25

Azeem Azhar uses Meta's Muse — instantly the top free iPhone app in the US — to probe the promise and peril of personal AI butlers.

Key points:

Muse users already get real tasks done: one recovered $250 in Delta flight-delay compensation within five minutes; the author's own OpenClaw agent books restaurants, files refunds, and complains to hotels over WhatsApp.
With 95%+ of users already on Facebook, 3M downloads isn't impressive; 500K early users is the real number to watch, alongside DAU and completed tasks.
Zuckerberg says Meta will take a small transaction fee; Walmart, Best Buy, Sephora, and Expedia are signed up. The interesting partner is Shopify's long tail of niche sellers that Google never reached well. Amazon blocked Muse because its ads made $68B last year — agents don't window-shop — yet Amazon runs its own Buy for Me agent.
The core problem: if Expedia pays Meta, the butler's loyalty follows the coin. A recent preprint documents "economic misalignment in personal AI agents" — LLMs gauge user wealth and steer toward pricier options.
Architecturally, Muse gives each user an isolated cloud VM with parallel sub-agents to mask latency, plus a "Confidential VM" even Zuck can't access — an Apple-style privacy playbook Apple itself is unlikely to match soon, since agent errors on long-horizon tasks are exactly what Apple hates.
Consumer agents will be won by trust and subtle interactions, not distribution: the butler must work for you.
