Chapter 1: What is the main topic discussed in this episode?
Here's your afternoon TNB Tech Minute for Friday, February 27th. I'm Julie Chang for The Wall Street Journal. We exclusively report that officials at multiple federal agencies have raised concerns about the safety and reliability of Elon Musk's XAI artificial intelligence tools in recent months. That's according to people familiar with the matter.
The warnings preceded the Pentagon's decision this week to put XAI at the center of some of the nation's most sensitive and secretive operations by allowing its chatbot Grok to be used in classified settings. Anthropic was the only developer approved for classified use before the deal between XAI and the military, but sources say some U.S. officials view Anthropic as too woke.
Chapter 2: What concerns do federal agencies have about Elon Musk's Grok chatbot?
and prefer Grok for its looser controls and Musk's stance on free speech. Other officials questioned whether Grok presents risks. Paramount has won the bidding war for Warner Bros. Discovery after Netflix declined to match Paramount's $31 per share offer.
The deal will now face scrutiny from federal regulators as it would put two legacy movie and TV studios under one roof, along with multiple cable networks. Paramount will own not only Warner Brothers and HBO, but also many popular cable networks including CNN, TNT, TBS, and The Food Network.
And President Trump's media company is discussing spinning off businesses, including social media platform Truth Social, into a new publicly traded company following its merger with TAE Technologies. In December, Trump Media agreed to merge with fusion energy company TAE Technologies in a $6 billion deal.
In a potential transaction, shares of the newly formed company would be distributed to Trump Media and technology shareholders before the TAE merger closes. The new company would then merge with a special purpose acquisition company. The companies said discussions about the potential spinoff are ongoing and that no definitive agreements have been reached.
Any transaction would be subject to approvals. And that's it for your TMB Tech Minutes.
