On the First Day without X, Many Brazilians Say They Feel Disconnected from the World

The blocking of social media platform X in Brazil divided users and politicians over the legitimacy of the ban, and many Brazilians on Saturday had difficulty and doubts over navigating other social media in its absence.

The shutdown of Elon Musk’s platform started early Saturday, making it largely inaccessible on both the web and through mobile apps after the billionaire refused to name a legal representative to the country, missing a deadline imposed by Supreme Court Justice Alexandre de Moraes. The blockade marks an escalation in a monthslong feud between Musk and de Moraes over free speech, far-right accounts and misinformation.

Brazil is one of the biggest markets for X, with tens of millions of users.

“I've got the feeling that I have no idea what’s happening in the world right now. Bizarre,” entertainment writer and heavy X user Chico Barney wrote on Threads. Threads is a text-based app developed by Instagram that Barney was using as an alternative. “This Threads algorithm is like an all-you-can-eat restaurant where the waiter keeps serving things I would never order.”

Bluesky, a social media platform that was launched last year as an alternative to X and other more established sites, has seen a large influx of Brazilians in the past couple of days. The company said Friday it has seen about 200,000 new users from Brazil sign up during that time, and the number “continues to grow by the minute.” Brazilian users are also setting records for activities such as follows and likes, Bluesky said.

Previous users of other platforms welcomed Brazilians to their ranks. “Hello literally everyone in Brazil,” a user wrote on Threads. “We're a lot nicer than Twitter here,” said another.

Platform migration isn't new for Brazilians. They were huge adopters of Orkut and, when Orkut went kaput, they very gladly moved to other platforms.

X is not as popular in Brazil as Facebook, Instagram, YouTube or TikTok. However, it remains an important platform on which Brazilians engage in political debates and is highly influential among politicians, journalists and other opinion makers.

It's also where they share their sense of humor. Many of the country’s most famous memes originate from posts on X before spreading to other social networks. Last week, for instance, Brazilians collaboratively crafted an absurd storyline for a fictional telenovela, complete with a theme song created using artificial intelligence tools.

Pop stars and their fanbases were also hit by Brazilians being left off the platform.

“Wait a lot of my fan pages are Brazilian!!! Come back hold up!!,” Cardi B said Friday on X. A fan page dedicated to Timothée Chalamet, known by the handle TimotheeUpdates, said it would temporarily cease updating as all of its administrators are Brazilian.

De Moraes said X will stay suspended until it complies with his orders, and he also set a daily fine of 50,000 reais ($8,900) for people or companies using virtual private networks, or VPNs, to access it. Some legal experts questioned the grounds for that decision and how it would be enforced. Others suggested the move was authoritarian.

The Brazilian Bar Association said Friday in a statement that it would request the Supreme Court review the fines imposed on all citizens using VPNs or other means to access X without due process. Brazil's bar association argued that sanctions should never be imposed summarily before ensuring an adversarial process and the right to full defense.

“I’ve used VPNs a lot in authoritarian countries to continue accessing news sites and social networks,” Maurício Santoro, a political science professor at the State University of Rio de Janeiro, said on the platform before its shutdown. “It never occurred to me that this type of tool would be banned in Brazil. It’s dystopian.”

A search Friday on X showed hundreds of Brazilian users inquiring about VPNs that could potentially enable them to continue using the platform by making it appear they are logging on from outside the country.

“Tyrants want to turn Brazil into another commie dictatorship but we won’t back down. I repeat: do not vote on those who don’t respect free speech. Orwell was right,” right-wing congressman Nikolas Ferreira, one of former President Jair Bolsonaro’s closest allies, published before X went off. Musk replied with an emoji suggesting agreement: “100”.

Ferreira is a 28-year-old YouTuber who received the most votes of the 513 elected federal lawmakers in the 2022 election. De Moraes ordered the block of his social media accounts after a mob of Bolsonaro supporters attacked Brazil’s Congress, presidential palace and Supreme Court in January 2023 seeking to overturn the election.

Lawmaker Bia Kicis said “the consequences of Alexandre de Moraes’ attacks to Elon Musk, X and Starlink will be regrettable for Brazilians.” She also urged Rodrigo Pacheco, the president of the country’s Senate, to act. Kicis has repeatedly urged Pacheco to open impeachment proceedings against the Supreme Court justice.

“We need to leave this state of apathy and stop the worst from happening,” the pro-Bolsonaro lawmaker, whose profiles were temporarily blocked by de Moraes in 2022, also said.

The former president said Saturday on Instagram that X's departure from Brazil was “another blow to our freedom and legal security.”

“It not only affects our freedom of expression, but also undermines the confidence of international companies in operating on Brazilian soil, with impacts ranging from national security to the quality of the information that reaches our citizens,” Bolsonaro said.

On Friday, President Luiz Inácio Lula da Silva backed de Moraes’ decision and took aim at Musk for positioning himself as though he was above the law during an interview with Radio MaisPB.

“Any citizen, from anywhere in the world, who has investments in Brazil, is subject to the Brazilian Constitution and Brazilian laws. Therefore, if the Supreme Court has made a decision for citizens to comply with certain things, they either have to comply or take another course of action,” Lula said. “It’s not because the guy has a lot of money that he can disrespect it.”

Ana Júlia Alves de Oliveira, an 18-year-old student, shared that many young people like her no longer watch newscasts or read newspapers, relying solely on social media platforms like X for their news. Without this platform, she felt disconnected.

“I kind of lost touch with what’s going on around the world,” she said. “I saw a lot of entertainment there too, so this is a new reality for me.”

AI to Track Icebergs Adrift at Sea in Boon for Science

British scientists said Thursday that a world-first AI tool to catalogue and track icebergs as they break apart into smaller chunks could fill a "major blind spot" in predicting climate change.

Icebergs release enormous volumes of freshwater when they melt on the open water, affecting global climate patterns and altering ocean currents and ecosystems, reported AFP.

But scientists have long struggled to keep track of these floating behemoths once they break into thousands of smaller chunks, their fate and impact on the climate largely lost to the seas.

To fill in the gap, the British Antarctic Survey has developed an AI system that automatically identifies and names individual icebergs at birth and tracks their sometimes decades-long journey to a watery grave.

Using satellite images, the tool captures the distinct shape of icebergs as they break off -- or calve -- from glaciers and ice sheets on land.

As they disintegrate over time, the machine performs a giant puzzle problem, linking the smaller "child" fragments back to the "parent" and creating detailed family trees never before possible at this scale.

It represents a huge improvement on existing methods, where scientists pore over satellite images to visually identify and track only the largest icebergs one by one.

The AI system, which was tested using satellite observations over Greenland, provides "vital new information" for scientists and improves predictions about the future climate, said the British Antarctic Survey.

Knowing where these giant slabs of freshwater were melting into the ocean was especially crucial with ice loss expected to increase in a warming world, it added.

"What's exciting is that this finally gives us the observations we've been missing," Ben Evans, a machine learning expert at the British Antarctic Survey, said in a statement.

"We've gone from tracking a few famous icebergs to building full family trees. For the first time, we can see where each fragment came from, where it goes and why that matters for the climate."

This use of AI could also be adapted to aid safe passage for navigators through treacherous polar regions littered by icebergs.

Iceberg calving is a natural process. But scientists say the rate at which they were being lost from Antarctica is increasing, probably because of human-induced climate change.

 


AMD Predicts Weaker First-Quarter Sales, Shares Plunge on Nvidia Comparisons

AMD Predicts Weaker First-Quarter Sales, Shares Plunge on Nvidia Comparisons

Advanced Micro Devices on Tuesday forecast a slight decline in quarterly revenue, raising concerns about whether it ​can effectively challenge Nvidia in the booming AI market and sending its shares tumbling 8% in after-hours trade.

The lackluster prediction comes despite an unexpected boost from sales of certain artificial intelligence chips to China, which began in the last quarter after the Trump administration approved a license for orders that AMD received in early 2025.

And without those sales to China which generated $390 million, AMD's data-center segment would have missed estimates for the fourth quarter.

AMD said it expects revenue of about $9.8 billion this quarter, plus or minus $300 million. That's down from $10.27 billion in the fourth-quarter which was up 34% year-on-year and ahead of LSEG ‌estimates for $9.67 billion.

PALES ‌NEXT TO NVIDIA

Though AMD is seen as one of the ‌few ⁠contenders ​that can seriously ‌challenge Nvidia, investors noted the stark contrast between the two companies' performances. AMD expects an adjusted gross margin of 55% this quarter. Nvidia has said it expects adjusted gross margin in the mid-70% range during its fiscal 2027.

"The expectations for large blowout quarters for AI-related hardware companies have skewed what the market is looking for," said Bob O'Donnell, president of TECHnalysis Research.

The forecast for the current first quarter includes $100 million from sales to China, where the situation remains "dynamic," AMD CEO Lisa Su said on a conference call with investors.

The US government ⁠has placed restrictions on the exports of advanced chips to China, but AMD received licenses to sell modified versions of its MI300 series ‌of AI chips there. Its MI308 chip competes with Nvidia's H20 ‍chip in China.

OPENAI SALES

AMD has accelerated its ‍product launches and is moving into selling full AI systems to better compete against Nvidia, which now ‍provides "rack-scale" systems that combine GPUs, CPUs and networking gear.

Last year, it entered into a multi-year deal to supply AI chips to ChatGPT-owner OpenAI, which would bring in tens of billions of dollars in annual revenue and give the startup the option to buy up to roughly 10% of the chipmaker.

Su reiterated on Tuesday that the company ​expects sales of a new flagship AI server to OpenAI and others to rise rapidly in the second half of this year, saying a global memory-chip crunch will not ⁠slow its plans.

"I do not believe that we will be supply-limited in terms of the ramp that we put in place," Su said.

BEYOND OPENAI

As Big Tech and governments across the globe double down on investing in AI hardware, shares in Santa Clara, California-based AMD have doubled since the start of 2025, outperforming a 60% bump in the broader chip index.

But analysts remain concerned that AMD's success remains tied to a handful of customers that rivals such as Nvidia could try to poach. Reuters reported this week that Nvidia made a $20 billion move to hire most of chip startup Groq's founders after OpenAI held chip supply discussions with the startup.

"Growth appears concentrated in large deployments and specific regions, and China shipments are significant enough to influence a quarter," said eMarketer analyst Gadjo Sevilla.

Revenue in AMD's key data-center segment grew 39% to $5.38 billion in the ‌fourth quarter. But excluding sales of the MI308, which is a data-center chip, that revenue would have been $4.99 billion, below estimates of $5.07 billion.

Switch 2 Sales Boost Nintendo Results but Chip Shortage Looms

The runaway success of the Switch 2 console drove up Nintendo's net profit by more than 50 percent in the nine months to December, the Japanese video game giant said Tuesday.

But a global memory chip shortage, created by frenzied demand for artificial intelligence hardware, could push up manufacturing costs.

The Switch 2 became the world's fastest-selling games console after launching to a fan frenzy last summer.

It is the successor to the original Switch, which soared in popularity during the pandemic when games such as "Animal Crossing" struck a chord during long lockdowns.

Both are hybrid devices that can be connected to a TV or used on-the-go.

In April-December, net profit jumped 51.3 percent year-on-year to 358.9 billion yen ($2.3 billion), and revenue nearly doubled on-year to 1.9 trillion yen, Nintendo said.

But the firm kept its annual unit sales target for the Switch 2 steady at 19 million, and also held its full-year net profit forecast of 350 billion yen.

"Nintendo Switch 2 got off to a good start following its launch on June 5 and unit sales continued to grow through the holiday season," the company said.

Nearly 17.4 million Switch 2 devices were sold in the nine-month period, it added.

"Maintaining momentum is certainly a big focus for Nintendo," Krysta Yang of the Nintendo-focused Kit and Krysta Podcast told AFP.

A lack of heavy-hitting first-party new games for the Switch 2 in coming months risks hindering growth, although third-party titles such as "Resident Evil Requiem" should help fill the gap, she said.

Nintendo said Tuesday it planned to release "Mario Tennis Fever" this month and "Pokemon Pokopia" in March.

While the firm is diversifying into hit movies and theme parks, consoles remain the core of its business.

The Switch 1 has now sold 155.37 million units -- overtaking the Nintendo DS console to be its best-selling hardware of all time.

But soaring prices for memory chips, used in gaming consoles as well as phones, laptops and other electronics, will likely be a headwind for the company.

Their prices have been pushed up as chipmakers focus on producing the advanced memory chips in huge demand to power AI data centers.

"Nintendo and other console manufacturers are publicly keeping quiet about the impact of the shortage," gaming industry consultant Serkan Toto told AFP.

But "users can forget the past when consoles always became cheaper in tandem with component costs falling over time", with price hikes potentially on the way in 2026, he said.

Yang said she thought a price increase for the Switch 2 "is not out of the question" but added that Nintendo "would likely exhaust all other options" before doing so.
