U.S. wireless giants AT&T and Verizon had big plans last year to advertise why customers should upgrade their phones and start using 5G wireless.

Then the pandemic hit, and with everyone stuck at home, showing off blazing speeds and consumer use cases in stadiums, airports and public places wasn’t just irrelevant — it was gauche. Cloud gaming, checking instant odds on gambling apps from stadiums and downloading Netflix movies at the airport became far less important than the ability to work from home — a better message for cable companies who already deliver high-speed home broadband.

“We almost lost the year,” said David Christopher, EVP of partnerships & 5G ecosystem development for AT&T. “But now, people are excited to get out of their homes and experience 5G in the wild. We will dramatize use cases that matter to customers.”

AT&T and Verizon want to transfer customers as fast as possible to 5G networks — not just to recoup the heavy capital expenditure costs of building out updated nationwide networks but also to lock in customers and keep them from defecting to T-Mobile.

Both AT&T and Verizon have offered promotional pricing this year on 5G phones to retain customers and entice new ones. But T-Mobile tends to offer the cheapest prices among the big three, while also topping both Verizon and AT&T in download speed and 5G availability, according to Open Network’s July 2021 5G User Experience Report.

“A focus on 5G isn’t going to be flattering to either Verizon or AT&T,” said Craig Moffett, a wireless analyst at MoffettNathanson. “They are falling far behind T-Mobile in what will soon matter most: 5G speed and coverage. And they charge consumers much higher prices than T-Mobile.”

That puts pressure on both companies to sell consumers on why they should choose AT&T and Verizon — making 5G a marketing challenge as Americans emerge from pandemic quarantines.

Convincing consumers

Getting Americans excited about 5G may not be easy.

A J.D. Power survey last year found that only about a quarter of wireless subscribers said they believed 5G would be significantly faster than current 4G LTE technology, and only 5% of respondents said they’d be willing to pay more for 5G service. 

Even the CEO of AT&T Communications, Jeff McElfresh, told CNBC last year he has “always tried to soften folks’ expectations around 5G.”

Much of the messaging about 5G so far has been about enterprise solutions. A Deloitte Insights consumer survey this year found that consumer use cases that demand the faster network simply don’t exist yet.

Verizon last year helped produce a documentary on 5G called “Speed of Thought,” which showed enterprise-focused examples, such as a robotic arm that a physician can use from anywhere and an augmented reality helmet for firefighters to help see through smoke. It also explored cities testing out 5G-enabled technology to avoid car collisions.

AT&T leaders have also said 5G’s real opportunity is in the business cases, particularly in the case of machines and equipment that are communicating via internet-of-things technology.

But both companies plan to illustrate specific consumer use cases in advertisements in the coming months to convince customers to upgrade.

In an outline of its 5G strategy for this year, AT&T detailed use cases including AR-aided shopping experiences for consumers in stores and downloading content at airports. Earlier this year, AT&T announced it would give its customers access to Bookful, which creates augmented reality experiences around books to try to improve reading comprehension. Christopher said viewing a street map through a phone is reliable and seamless in 5G, more easily allowing for activity like an augmented reality guide to a city, whereas it would have consistently lagged with 4G. 

Verizon is currently running a number of 5G-related TV ad spots, including those with “Saturday Night Live” star Kate McKinnon about a promotion to receive $800 for a 5G phone when consumers trade in their old device.

Verizon has also done some marketing around what its 5G will do for gaming, both in its Super Bowl spot earlier this year and a digital video released in May that tried to illustrate what video game-like lag would look like in everyday life

But the Verizon campaigns don’t yet show why 5G is necessary or important for average consumers.

In one recent Verizon ad, viewers see a series of images — a man climbing a cell tower, a thunderstorm, cars driving on the street, landscape shots of cities — with voiced-over statements about “next generation service,” “broader spectrum,” and “the more going the extra mile matters.” But the only clear consumer use case shown in the one-minute commercial is video chatting — an activity that doesn’t require 5G.

It’s possible 5G advertising could backfire on both companies if consumers view networks as interchangeable and simply choose the lowest-price offering — which will be T-Mobile, Moffett said.

Christopher points out that educating consumers about 5G will benefit the entire industry. “We’re not going to spend our resources talking about the other guy,” he said. “Everything educates the customer about the broad benefits of 5G as a category, and that’s a good thing, too. We’re happy with that.”

Verizon’s 5G Home strategy

Verizon’s 5G marketing strategy hasn’t kicked into full gear yet because the company still hasn’t lit up its nationwide footprint of C-Band spectrum, said Manon Brouillette, recently named Verizon Consumer Group’s chief operating officer and deputy chief executive officer. Verizon CEO Hans Vestberg has promised 100 million Americans will have access to speeds up to 1 Gigabit per second by March 2022.

Brouillette she believes 5G’s biggest selling point is as a replacement for cable broadband once Verizon’s so-called “ultra wideband” network in fully functional. Verizon spent nearly $53 billion on the airwaves earlier this year.

“When it comes to messaging, we need to make sure that any consumer understands you don’t need fiber to home anymore,” Brouillette said. “When C-band is here, we can make a sales pitch where we’ll offer one product, in-home and out-of-home, at low latencies, that has never been offered before. That’s the true game changer.”

Verizon already offers 5G Home that runs on millimeter wave technology — faster than C-band — to parts of 47 U.S. cities.

But even when Verizon’s 5G network is up and running across the country, the company still plans on selling separate products — mobile and home — even though they’ll operate on the same network. Verizon currently sells its 5G Home product at a $20 monthly discount for customers that also buy Verizon wireless.

Verizon is planning more “creative” ways to price home and mobile internet together in 2022, said Brouillette. But that packaging may not be enough to convince consumers to switch to Verizon — especially as cable companies such as Comcast and Charter offer their own mobile services (which use Verizon’s own network) with bundled discounts.

“It’s a myth believing one major ad campaign will solve everything,” said Brouillette. “It will come down to performance and execution.”

People with ADHD, autism, dyslexia say AI agents are helping them succeed at work

People with ADHD, autism, dyslexia say AI agents are helping them succeed at work

Neurodiverse professionals may see unique benefits from artificial intelligence tools and agents, research suggests. With AI agent creation booming in 2025, people with conditions like ADHD, autism, dyslexia and more report a more level playing field in the workplace thanks to generative AI.

A recent study from the UK’s Department for Business and Trade found that neurodiverse workers were 25% more satisfied with AI assistants and were more likely to recommend the tool than neurotypical respondents.

“Standing up and walking around during a meeting means that I’m not taking notes, but now AI can come in and synthesize the entire meeting into a transcript and pick out the top-level themes,” said Tara DeZao, senior director of product marketing at enterprise low-code platform provider Pega. DeZao, who was diagnosed with ADHD as an adult, has combination-type ADHD, which includes both inattentive symptoms (time management and executive function issues) and hyperactive symptoms (increased movement).

“I’ve white-knuckled my way through the business world,” DeZao said. “But these tools help so much.”

AI tools in the workplace run the gamut and can have hyper-specific use cases, but solutions like note takers, schedule assistants and in-house communication support are common. Generative AI happens to be particularly adept at skills like communication, time management and executive functioning, creating a built-in benefit for neurodiverse workers who’ve previously had to find ways to fit in among a work culture not built with them in mind.

Because of the skills that neurodiverse individuals can bring to the workplace — hyperfocus, creativity, empathy and niche expertise, just to name a few — some research suggests that organizations prioritizing inclusivity in this space generate nearly one-fifth higher revenue.

AI ethics and neurodiverse workers

“Investing in ethical guardrails, like those that protect and aid neurodivergent workers, is not just the right thing to do,” said Kristi Boyd, an AI specialist with the SAS data ethics practice. “It’s a smart way to make good on your organization’s AI investments.”

Boyd referred to an SAS study which found that companies investing the most in AI governance and guardrails were 1.6 times more likely to see at least double ROI on their AI investments. But Boyd highlighted three risks that companies should be aware of when implementing AI tools with neurodiverse and other individuals in mind: competing needs, unconscious bias and inappropriate disclosure.

“Different neurodiverse conditions may have conflicting needs,” Boyd said. For example, while people with dyslexia may benefit from document readers, people with bipolar disorder or other mental health neurodivergences may benefit from AI-supported scheduling to make the most of productive periods. “By acknowledging these tensions upfront, organizations can create layered accommodations or offer choice-based frameworks that balance competing needs while promoting equity and inclusion,” she explained.

Regarding AI’s unconscious biases, algorithms can (and have been) unintentionally taught to associate neurodivergence with danger, disease or negativity, as outlined in Duke University research. And even today, neurodiversity can still be met with workplace discrimination, making it important for companies to provide safe ways to use these tools without having to unwillingly publicize any individual worker diagnosis.

‘Like somebody turned on the light’

As businesses take accountability for the impact of AI tools in the workplace, Boyd says it’s important to remember to include diverse voices at all stages, implement regular audits and establish safe ways for employees to anonymously report issues.

The work to make AI deployment more equitable, including for neurodivergent people, is just getting started. The nonprofit Humane Intelligence, which focuses on deploying AI for social good, released in early October its Bias Bounty Challenge, where participants can identify biases with the goal of building “more inclusive communication platforms — especially for users with cognitive differences, sensory sensitivities or alternative communication styles.”

For example, emotion AI (when AI identifies human emotions) can help people with difficulty identifying emotions make sense of their meeting partners on video conferencing platforms like Zoom. Still, this technology requires careful attention to bias by ensuring AI agents recognize diverse communication patterns fairly and accurately, rather than embedding harmful assumptions.

DeZao said her ADHD diagnosis felt like “somebody turned on the light in a very, very dark room.”

“One of the most difficult pieces of our hyper-connected, fast world is that we’re all expected to multitask. With my form of ADHD, it’s almost impossible to multitask,” she said.

DeZao says one of AI’s most helpful features is its ability to receive instructions and do its work while the human employee can remain focused on the task at hand. “If I’m working on something and then a new request comes in over Slack or Teams, it just completely knocks me off my thought process,” she said. “Being able to take that request and then outsource it real quick and have it worked on while I continue to work [on my original task] has been a godsend.”

Underwater cables are a vital piece of the AI buildout and internet — investment is booming

Underwater cables are a vital piece of the AI buildout and internet — investment is booming

Over 95% of international data and voice call traffic travels through nearly a million miles of underwater communication cables.

These cables carry government communications, financial transactions, email, video calls and streaming around the world.

The first commercial telecommunication subsea cable was used for telegraphs and was laid across the English Channel between Dover, England and Calais, France in 1850.

The technology then evolved to coaxial cables that carried telephone conversations, and most recently, fiber optics that ferry data and the internet as we know it.

“About ten years ago, we saw the advent of another big category, which is the webscale players and the likes of Meta, Google, Amazon, etc., who represent now probably 50% of the overall market,” said Paul Gabla, chief sales officer at Alcatel Submarine Networks.

Alcatel is the world’s largest subsea cable manufacturer and installer, according to industry trade magazine Submarine Telecoms Forum.

Demand for subsea cables is increasing as tech giants race to develop computation-intensive artificial intelligence models and connect their growing networks of data centers.

Investment into new subsea cable projects is expected to reach around $13 billion between 2025-2027, almost twice the amount that was invested between 2022 and 2024, according to telecommunications data provider firm TeleGeography.

Big Tech, big cables

“AI is increasing the need that we have for subsea infrastructure,” said Alex Aime, vice president of network investments at Meta. “Oftentimes when people think about AI, they think about data centers, they think about compute, they think about data. But the reality is, without the connectivity that connects those data centers, what you have are really expensive warehouses.”

In February, the company announced Project Waterworth, a 50,000km (31,000-mile) cable that will connect five continents, making it the world’s longest subsea cable project.

Meta will be the sole owner of Waterworth, which the company says will be a multi-year, multi-billion-dollar project.

Amazon also recently announced its first wholly-owned subsea cable project called Fastnet.

Fastnet will connect Maryland’s eastern shore to County Cork, Ireland, and capacity will exceed 320 terabits per second, which is equivalent to streaming 12.5 million HD movies simultaneously, according to Amazon.

“Subsea is really essential for AWS and for any connectivity internationally across oceans,” Matt Rehder, Amazon Web Services vice president of core networking, told CNBC in an interview about Amazon’s subsea cable investments. “Without subsea you’d have to rely on satellite connectivity, which can work. But satellite has higher latency, higher costs, and you just can’t get enough capacity or throughput to what our customers and the internet in general needs.”

Google is another large player, having invested in over 30 subsea cables.

One of the company’s latest projects is Sol, which will connect the U.S., Bermuda, the Azores and Spain.

Microsoft has also invested in the infrastructure.

“You’ve seen this huge growth in submarine cables over the past 20 years. And this is driven by just a voracious demand for data,” says Matthew Mooney, director of global issues at cybersecurity firm Recorded Future.

Cut cables

“When you have so many vessels in international waters that are highly trafficked by lots of commercial vessels or fishing vessels, the likelihood of accidents is fairly high,” Murphy said. “But if you’re a hostile actor, you know that as well. So if you’re sending out the so-called Russian ghost fleet, or if you have a Chinese fishing vessel and a cable is accidentally cut, you could just say, ‘Oh, well, it was an accident.’ But it could be intentional. So it’s really hard to discern sometimes when an act of damage is actually intentional or accidental.”

Mooney and Recorded Future have been tracking some of these cases of suspected sabotage.

“I would say that we have seen a significant uptick in what we would consider intentional damages,” Mooney said. “In 2024 and 2025, [we] saw a notable increase in incidents that occurred in the Baltic Sea and around Taiwan. And so it is difficult to be able to determine with 100% validity that these are intentional. However, the fact patterns that emerge from these events does give you cause to be suspicious that they could all be considered accidental.”

Mooney said the increase in suspected sabotage has corresponded to increased tensions between Russia and Ukraine and China and Taiwan.

Despite there being a lack of concrete evidence of subsea cable sabotage, governments are taking the threat seriously.

In January, NATO launched the “Baltic Sentry” following several incidents of cable cuts in the Baltic Sea. The operation involves deploying drones, aircraft and subsea and surface vessels to safeguard the subsea infrastructure in the region.

“As a result, I don’t believe we’ve seen any instances of cable severing since late January 2025, in the Baltic Sea,” Mooney said.

A picture taken on February 4, 2025 shows a Helicopter 15 (HKP15) (L) on the flight deck of patrol ship HMS Carlskrona (P04) on open water near Karlskrona, Sweden, as part of the NATO Baltic Sea patrol mission, the Baltic Sentry, aimed to secure critical underwater infrastructure. The patrol ship HMS Carlskrona (P04) set off from the naval port in Karlskrona on February 4, 2025 to become part of NATO’s Baltic Sentry operation as one of several Swedish ships that are part of Standing NATO Maritime Group One (SNMG1). This is the first time the ship has hoisted the NATO flag on board. The purpose of NATO’s Baltic Sentry operation is to demonstrate presence and secure critical underwater infrastructure.

U.S.-China tension

In the United States, the Federal Communications Commission, which is responsible for granting licenses to anyone wishing to install or operate subsea cables connecting to the U.S., has introduced tighter rules on foreign firms building this infrastructure, citing security concerns.

“One area we’ve been particularly focused on are threats that come from the Chinese Communist Party as well as from Russia,” FCC Chair Brendan Carr told CNBC. “So we’re taking actions right now to make it difficult or effectively prohibiting the ability to connect undersea cables directly from the U.S. to a foreign adversary nation.”

Carr said the FCC is also taking steps to make sure the hardware itself isn’t compromised, not allowing Huawei, ZTE or other questionable “spy gear” to be used in undersea cables.

In July, three House Republicans sent a letter to the CEOs of Meta, Amazon, Google and Microsoft asking if the companies have used PRC-affiliated cable maintenance providers.

In response to CNBC’s question about the letter, Meta’s Aime said, “We do not work with any Chinese providers of cable systems on systems that we’ve announced, and we are in full compliance with U.S. policy regulations around partners in the ecosystem and the supply chain.”

Amazon also told CNBC it does not work with Chinese companies.

Microsoft and Google did not return CNBC’s request for comment on the letter.

To understand how subsea cables work, CNBC visited Alcatel Submarine Networks subsea cable manufacturing facilities in Calais, France and Greenwich, England. We also spoke to government officials and tech giants to find out why subsea cables are crucial to keeping us connected and what we can do to protect this critical infrastructure.

Palantir CEO Karp twice slams short sellers as stock suffers worst week since April

With Palantir’s stock plummeting more than 11% this week despite a better-than-expected earnings report, CEO Alex Karp took aim at investors betting against the software company.

Karp, who co-founded Palantir in 2003, went after short sellers in two separate interviews on CNBC this week. After “Big Short” investor Michael Burry revealed bets against Palantir and Nvidia, Karp on Tuesday accused short sellers of “market manipulation.”

He repeated that message on Friday in an interview with CNBC’s Sara Eisen, again knocking Burry’s wager against the stock.

“To get out of his position, he had to screw the whole economy by besmirching the best financials ever … that are helping the average person as investors [and] on the battlefield,” Karp said.

Even with Palantir’s slide this week, the stock is up 135% in 2025 and has multiplied 25-fold in the past three years, an extended rally that’s lifted the company’s market cap to over $420 billion. While revenue and profit are growing rapidly, the multiples have shot up much faster, and the stock now trades for about 220 times forward earnings, a ratio that rivals Tesla’s.

Nvidia and Meta, by contrast, have forward price-to-earnings ratios of about 33 and 22, respectively.

In August, Citron Research’s Andrew Left, a noted short seller, called Palantir “detached from fundamentals and analysis” and said shares should be priced at $40. It closed on Friday at $177.93 after late-day gains pushed the stock into the green.

Palantir, which builds analytics tools for large companies and government agencies, reported earnings and revenue on Monday that topped analysts’ estimates and issued a forecast that was also ahead of Wall Street projections.

But the stock fell about 8% after the report and then slid almost 7% on Thursday. Karp told Eisen that the recent boom in Palantir’s share price isn’t just for Wall Street.

“We’re delivering venture results for retail investors,” he said.

While Palantir has in the past faced a fairly heft dose of short interest, there are currently relatively few investors placing big bets against it. The short interest ratio, or the percentage of outstanding shares being sold short, peaked at over 9% in September and is now at a little over 2%, which is about as low as its been since the company went public in 2020.

Still, calling out the doubters is a common occurrence for Karp, who has previously said on CNBC that people should “exit” if they “don’t like the price.”

In May, after the stock plummeted following earnings, Karp said ,”You don’t have to buy our shares.”

“We’re happy,” he said. “We’re going to partner with the world’s best people and we’re going to dominate. You can be along for the ride or you don’t have to be.”

The company has also faced backlash over its work with government agencies like U.S. Immigration and Customs Enforcement, and Karp has admitted that his strong pro-Israel stance led some people to leave the company.

The boisterous CEO has been particularly vocal this week. On Monday’s earnings call, he questioned how happy the people are who didn’t invest in the company, and told them to “get some popcorn.”

And on CNBC he aimed much of his ire at Burry after the investor revealed his short positions in Palantir and Nvidia.

“The two companies he’s shorting are the ones making all the money, which is super weird,” Karp told CNBC’s “Squawk Box” on Tuesday. “The idea that chips and ontology is what you want to short is bats— crazy.”
