[Meta Tests Human Proxy Muse for Making Calls, Rolls Back Feature After Privacy Controversy] Deep Tide TechFlow reports that on September 23, Meta tested a human concierge service for its personal AI assistant Muse, where human contractors made certain calls on behalf of users in the background. After raising employee privacy concerns, the company admitted that failing to disclose this properly was a mistake and temporarily rolled back the feature. Internal testing showed that human-made calls could achieve a success rate of 95% to 98%, higher than pure AI calls. Muse has surpassed 2.5 million downloads within two weeks of its release, and Meta's stock price has risen by over 20% during the same period.
