Serge Matta, president of GroundTruth, at an Axios event on 5G.

Serge Matta, President of global tech platform GroundTruth, said 5G is "very, very close" to impacting retail. Through the 5G network, stores in a mall could pinpoint customers' location, even while they are offline, through constant pinging in the network.

Why it matters: Matta predicts that 5G could push shoppers into stores by using their offline behaviors, which could help spark a rebound in retail.

Yes, but: As 5G strengthens, the tech world will need to confront privacy concerns. GroundTruth currently tracks 75 million people, and every single one had to "knowingly" give opt-in consent, Matta said.

"The consumer has to provide explicit consent we're tracking them"
— Matta

The big picture: Before 5G can help the retail industry get back on its feet, privacy concerns and regulations must be addressed within the network.

Biden's "overwhelming force" doctrine

President-elect Biden has ordered up a shock-and-awe campaign for his first days in office to signal, as dramatically as possible, the radical shift coming to America and global affairs, his advisers tell us. 

The plan, Part 1 ... Biden, as detailed in a "First Ten Days" memo from incoming chief of staff Ron Klain, plans to unleash executive orders, federal powers and speeches to shift to a stark, national plan for "100 million shots" in three months.

Episode 2: Barbarians at the Oval

Beginning on election night 2020 and continuing through his final days in office, Donald Trump unraveled and dragged America with him, to the point that his followers sacked the U.S. Capitol with two weeks left in his term. This Axios series takes you inside the collapse of a president.

Episode 2: Trump stops buying what his professional staff are telling him, and increasingly turns to radical voices telling him what he wants to hear. Read episode 1.

President Trump plunked down in an armchair in the White House residence, still dressed from his golf game — navy fleece, black pants, white MAGA cap. It was Saturday, Nov. 7. The networks had just called the election for Joe Biden.

Fringe right plots new attacks out of sight

Domestic extremists are using obscure and private corners of the internet to plot new attacks ahead of Inauguration Day. Their plans are also hidden in plain sight, buried in podcasts and online video platforms.

Why it matters: Because law enforcement was caught flat-footed during last week's Capitol siege, researchers and intelligence agencies are paying more attention to online threats that could turn into real-world violence.
