Cal AI founder, 19, raises $10M for Persona wristband

What happened: The 19 year old who sold Cal AI raised $10 million for Persona, an AI assistant that orders food and rides, books travel, and handles email. It is a free iMessage beta now, with a $179 wristband due in December. TechCrunch and Inc. reported the round.
The claim: Persona says the band won't always be listening.
Austin's take: Austin likes pairing a personal agent with hardware, which most current agents lack, and thinks $179 is fair, but notes Humane and Rabbit show how hard AI gadgets are.
Why it matters: Wearables are becoming the next fight for always available assistants.
What to do: Try the free iMessage beta before committing to hardware, and think about what personal data you'd hand an assistant on your wrist.
