Meta's personal AI agent Muse climbs to No. 1 among free apps on Apple's US App Store, ahead of ChatGPT; Muse launched on September 8 (Georgia Hennessy/Business Insider)

Meta’s Muse reaching No. 1 on the U.S. App Store signals how quickly consumer demand is shifting toward AI assistants that are embedded in major platforms, intensifying the competitive race with ChatGPT and other copilots. For CIOs and technology leaders, the strategic implication is that AI is becoming a mainstream interface for work and customer engagement, raising the bar for user experience, data governance, and vendor/platform choices across the enterprise. IT organizations should expect growing employee and business-unit demand for consumer-grade AI tools and plan for policies, security controls, and integration strategies that can support rapid adoption without creating shadow AI risk.
