Texas AG to investigate Meta and Character.AI over 'misleading' mental health claims

engadget.com Unknown 2025-11-21 15:13:43

Texas Attorney General Ken Paxton has announced plans to investigate both Meta AI Studio and Character.AI for offering AI chatbots that can claim to be health tools, and potentially misusing data collected from underage users. Paxton says that AI chatbots from either platform "can present themselves as professional therapeutic tools," to the point of lying about their qualifications. That behavior that can leave younger users vulnerable to misleading and inaccurate information. Because AI platf

Shamelessness as a strategy (2019)

news.ycombinator.com Nadia Asparouhova 2025-11-21 15:27:01

Shamelessness as a strategy I’ve enjoyed playing a game called Avalon recently. I won’t go too far into the rules, but it’s a hidden role game in the vein of Secret Hitler or Werewolf, where one team is “good”, trying to uncover who among them is “evil”, before the evil team wins. One of the characters you can play is Merlin. Merlin knows who the evil players are, but can’t reveal what he knows, because the evil team can kill Merlin and win the game. So Merlin relies on another character, Perc

This comes on the heels of the Duffer Brothers’ Upside Down Productions moving from Netflix to Paramount over the weekend.

As the sun continues the tumultuous peak of its 11-year cycle, more instances of aurora borealis have been expected. The most recent instance was earlier in August when auroras lit up the skies in 18 states. It seems the Earth is in for another battering of solar material as another aurora has been forecast for Monday night, and it should be a pretty decent one for states in the northern US. According to NOAA, the Earth will experience a geomagnetic storm with a Kp 5 rating. For the uninitiated

Britt Lower’s ‘Severance’ Audition Tape Proves Her Helly R. Was Meant to Be

Long before Severance became a TV obsession, when the Apple TV+ series was still being cast, an actor taped an audition scene for one of the show’s most complex and crucial roles. That clip has been released, and it’s incredible to see how the performer’s initial instincts for and interpretation of the character carried over almost note-perfectly into the show itself. Though viewers were first lured in by big names like Adam Scott, Christopher Walken, Patricia Arquette, and John Turturro, Sever

Nobody really understands how TPUs work…and neither do we! So we wanted to make this because we wanted to take a shot and try to guess how it works–from the perspective of complete novices! We wanted to do something very challenging to prove to ourselves that we can do anything we put our mind to. The reasoning for why we chose to build a TPU specifically is fairly simple: None of us have real professional experience in hardware design, which, in a way, made the TPU even more appealing since w

How much do electric car batteries degrade?

It’s always the battery in my mobile phone that gives up on me first. After just a few years, it can barely make it through the day without getting another charge. Most electric cars have the same types of batteries — usually lithium-ion — so the assumption is that they degrade just as quickly. This is a fairly common fear for people considering a new EV: “Won’t the battery need to be replaced after a few years?”.
