When 5G isn't really 5G

🐬 33% of them smile back: New research shows bottlenose dolphins “smile” at each other to signal playtime. In science speak, it’s a “prolonged open-mouth expression,” and it only happens when their friends are in view — never in other contexts. The video is adorable.

Range in value of the watches in Tom Brady’s collection. They’ll be auctioned off by Sotheby’s. The white gold and diamond watch he wore during his Netflix special, “Greatest Roast of All Time,” is the hot ticket, and it’s expected to go for $400,000 to $800,000. Yeah, I hear you — my $30 Timex does the same thing.

Amazon’s new lineup of Fire HD 8 tablets: They’ve got double the RAM of the previous models, a 5 MP rear cam, an 8-inch HD display, up to 13 hours of battery life, plus an AI webpage summary tool and a writing assistant. Good time to buy, too: The Fire HD 8 is 35% off right now, and the Fire HD 8 Kids and Fire HD 8 Kids Pro are both 50% off.

🧃 Out of juice: Enel X, the company behind JuiceBox EV chargers, is cutting all support in the U.S. Its home chargers will still work, but they’ll receive no more updates, apps or fancy features, like scheduling a charge. Customer support is gone, too. Send questions or claims to claimsagent@tplc-claims.com.

That was close: Security researchers found a flaw in Kia’s web portal. With just the license plate number and VIN, someone could hack in and remotely unlock doors, honk the horn and even start the engine. The portal didn’t verify dealer-level privileges. Oops. Kia says they’ve patched the vulnerability.

👓 Privacy nightmare: Two Harvard students used Meta’s smart glasses to create a tool that identifies any stranger walking by and pulls up their personal info. It scrapes the web to find where that person’s face appears, grabs their name, and digs up details like their home address, phone number and occupation. This is terrifying in the wrong (or any) hands.

Big Brother is watching: License plate reader systems were once used to track stolen cars and gather insurance data. Now, they’re snapping pics of political signs, abortion-rights bumper stickers and clothing with text. Millions of pics are uploaded every month to massive, searchable databases with precise locations for each image. Wild.

👀 Spy on me: TikTok is legally required to share user data with the Communist Chinese government, but a recent survey shows 68% of Americans don’t support banning the app. Arguments include: 1.) “The U.S. government has more access to info than China,” and 2.) “I’ve got nothing to hide.” My take: It’s not only about the data; it’s about China being able to use 170,000,000 devices in America for a coordinated cyberattack on our communications network, power grid or worse.

For ChatGPT maker OpenAI. They just raised $6.6 billion in funding. Some of the biggest investors include Thrive Capital, Microsoft, Nvidia and SoftBank. This surprised me: OpenAI expects to lose $5 billion in 2024. They have a heck of a lot of Nvidia GPUs to buy to power their models.

Pink Floyd’s payout for selling the rights to their recorded music, name and likeness. Sony now owns the British rock band’s catalog. I smell a virtual concert coming to a city near you, where you can be comfortably numb. Btw, digital avatars of ABBA do concerts seven days a week in a custom-built London arena with a 3,000-seat capacity. They make $2,000,000 per week!
