I'm looking at a Tuesday where the biggest AI story is that the bots are telling on their users — Meta's Muse is exposing private conversations to anyone who searches, a reminder that 'share' buttons have blast radii nobody reads. Meanwhile the regulators are done waiting for permission: the CFTC's new chairman wants federal rules for crypto exchanges, retail margin, and prediction markets without Congress holding his coat. Over in the trenches, the machines keep earning their keep — Mozilla used Claude to hunt down a record haul of latent Firefox security bugs, Perplexity figured out how to run serious AI workflows entirely on your own Mac, and a SpaceX alum just raised $115 million to make cargo planes fly themselves. The pattern of the day: the AI future is arriving faster than the guardrails, and today it was the guardrails that made the news.

• Meta Muse exposes users' personal and business secrets when they share conversations
  Source: Ars Technica RSS
  
  Meta's Muse chatbot is leaking personal and business secrets through its conversation-sharing feature — a single search query can surface thousands of shared conversations by title, exposing the private chats of users who apparently had no idea their 'shared' links were effectively public. The episode underscores how casually deployed AI products treat consent as a checkbox, and how the next big privacy scandal is already sitting in someone's indexed link history.
• TikTok staff raised child safety concerns, but executives reportedly failed to act

  TikTok employees raised alarms about child-safety risks internally and executives reportedly failed to act, according to court documents surfacing this week — staff described mounting frustration as their concerns about harms to children went nowhere up the chain. The documents add weight to a long-running pattern of safety teams sounding alarms inside large platforms and being overruled by the people running the growth engine.
• 🏴 The CFTC Isn't Waiting on Congress
  Source: Bankless RSS
  
  CFTC Chairman Mike Selig says he wants federal rules for crypto exchanges, retail margin trading, and prediction markets without waiting for Congress to pass market-structure legislation. His CTX and CAM proposals would bring retail margin activity onshore, put exchanges under one federal roof, and redraw the fight over prediction markets — the most aggressive assertion of derivatives-regulator turf in crypto's history.
• SpaceX alum's aviation startup, Reliable Robotics, lands $115M, topping $1B valuation
  Source: Techcrunch RSS
  
  Reliable Robotics, the aviation startup founded by SpaceX alumni, extended its Series D with $115 million in equity and $25 million in debt, pushing its valuation past $1 billion. The company is building autonomous flight systems for cargo aircraft — one of the quietest corners of the autonomy race, and one where the economics of pilotless freight could land before anyone's robotaxi finally does.
• Perplexity makes it easier to run AI workflows entirely on your own Mac
  Source: Engadget RSS
  
  Perplexity now lets owners of a Mac with at least 36GB of RAM run full AI workflows entirely on their own machine, with no cloud required. The move is part of a broader on-device AI push: keep the compute local, keep the data local, and make the cloud an option rather than a dependency — exactly the privacy story the day's other headlines were screaming for.
• Behind the Scenes Hardening Firefox with Claude Mythos Preview
  Source: Mozilla Hacks RSS
  
  Firefox just got its deepest security scrub in years: Mozilla identified and fixed an unprecedented number of latent security bugs in the browser with help from Claude Mythos Preview and other AI models, and a new behind-the-scenes post walks through how the AI-assisted hardening campaign actually worked. It's one of the clearest real-world cases of frontier models doing security work at scale — finding the cracks before someone else does.
