Jess started her career at TechRadar, covering news and hardware reviews.Tech YouTuber Matt Robb says that Muse gave out his home address to a total stranger this weekend, after authorizing the bot to handle his Facebook Marketplace account. “[Muse] didn’t tell me any of this until after the guy had left (luckily I’m in an apartment with security),” he added in a follow up post.The incident appears to have been caused by the way Muse was prompted to run Robb’s Facebook Marketplace page. Robb shared a Muse-generated summary of the incident with The Verge, in which the agent recounts being given “hands-off” control over replying to Marketplace messages.
