Paul Stenhouse: AI impersonator of Marco Rubio, Nvidia becomes first $4 trillion company, Samsung explores wearables

The US Secretary of State was impersonated using AI   Concerning news this week as it was revealed that at least three foreign ministers, a US governor, and a member of Congress all received outreach from the fake Rubio, according to a State Department cable.   The impersonator reached out to people using Signal, an app that allows you to choose any username you want – the impersonator used a fake state department email address to make it look legit. At least one of the targets was sent a text message, but at least two were sent Signal voice messages.   We're at a point now, or will reach it very soon, where we're going to need to figure out how to verify if the person you're chatting or talking to is who you think they are.     Nvidia becomes the first $4 trillion company   Apple was the first US company to hit $1 trillion in 2018, first to hit $2 trillion in 2020, and the first to hit $3 trillion in 2022, so by that math, it should have hit $4 trillion in 2024, but Nvidia beat them.   Nvidia only became a $1 trillion company in 2023 - two years ago!   For context, $4 trillion would be like giving all 5.3 million New Zealanders USD $750,000 (NZD $1.2 million).    Samsung is exploring new wearables   The electronics maker, who is known for leading with tech advancements, says they're exploring how people may want to interact with AI. Their current thinking is that the device shouldn't be carried, so are looking at glasses, earrings, watches, rings, a necklace, and would be a companion to a phone.      LISTEN ABOVE See omnystudio.com/listener for privacy information.
