Meta boss Mark Zuckerberg plans to ramp up spending on artificial intelligence (AI) projects this year, even as other executives warn of a potential bubble in the industry. During a call with financial analysts on Wednesday to discuss the Facebook-owner's 2025 financial results, the company said it expects to spend up to $135bn (£97bn) this year, mostly on infrastructure related to AI. That is nearly twice the $72bn Meta spent last year on AI projects and infrastructure. In the last three years, the technology giant has spent roughly $140bn in an attempt to get ahead of the AI boom. Zuckerberg said on Wednesday that he is expecting 2026 to be the year that AI dramatically changes the way we work.

The government has launched a series of free AI training courses designed to help people learn how to use the technology at work. The online lessons give advice on things such as how to prompt chatbots or use them to assist with admin tasks. Many of the courses are free, with others subsidised, and the government aims to reach 10 million workers by 2030 - calling it the most ambitious training scheme since the launch of the Open University in 1971. But the Institute for Public Policy Research (IPPR) has warned workers will need to know more than just how to prompt a chatbot as the workforce adapts to the growth of AI. Skills for the age of AI can't be reduced to short technical courses alone, said Roa Powell, senior research fellow at the IPPR.

Pope Leo XIV made his first address to the College of Cardinals on May 10, 2025 in Vatican City, and touched upon the rise of artificial intelligence. Pope Leo XIV made his first address to the College of Cardinals on May 10, 2025 in Vatican City, and touched upon the rise of artificial intelligence. As technologists race to accelerate AI's progress with minimal guardrails, they are being met with increasing resistance from a powerful global contingent: Christian leaders and their congregations. Christians are not a monolith by any means. But this year, Christian leaders across sects--including Catholics, Evangelicals, and Baptists--sounded the alarm on AI's potential impact on family, human relationships, labor, and the church itself.

The AI boom has caused as much carbon dioxide to be released into the atmosphere in 2025 as emitted by the whole of New York City, it has been claimed. The global environmental impact of the rapidly spreading technology has been estimated in research published on Wednesday, which also found that AI-related water use now exceeds the entirety of global bottled-water demand. The figures have been compiled by the Dutch academic Alex de Vries-Gao, the founder of Digiconomist, a company that researches the unintended consequences of digital trends. He claimed they were the first attempt to measure the specific effect of artificial intelligence rather than datacentres in general as the use of chatbots such as OpenAIâ s ChatGPT and Googleâ s Gemini soared in 2025. The figures show the estimated greenhouse gas emissions from AI use are also now equivalent to more than 8% of global aviation emissions.

Why an AI'godfather' is quitting Meta after 12 years Just a couple of weeks ago, one of the godfathers of artificial intelligence was in St James's Palace being handed an award from King Charles for his work in artificial intelligence (AI). Professor Yann LeCun was being honoured along with six other recipients for his contributions to the field, which have been credited as advancing deep learning. But Mr LeCun is at odds with some of the AI world over the future of the generation-defining technology. And now he is going all-in on his idea of advanced machine intelligence after announcing he is leaving his role as Meta's chief AI scientist to start a new firm. During his 12 years at the company, Prof LeCun won the prestigious Turing Award and witnessed several flurries of excitement around AI - not least the most recent boom in generative AI accelerated by rival OpenAI's launch of ChatGPT in late 2022.

Chip giant Nvidia beat Wall Street's expectations for revenue and upcoming sales, easing investor concerns about heavy artificial intelligence (AI) spending that have unsettled markets. In its quarterly earnings report on Wednesday, the firm said revenue for the three months to October jumped 62% to $57bn, driven by demand for its chips used in AI data centres. Sales from that division rose 66% to more than $51bn. Fourth-quarter sales forecasts in the range of $65bn also topped estimates, sending shares in Nvidia more than 3% higher in after-hours trading. Nvidia, the world's most valuable company, is seen as a bellwether for the AI boom.

On this episode of, guest Brian Merchant walks us through a historical framework he used to analyze whether AI fits the classic signs of an economic bubble--and what that means for all of us. Chatter about an AI bubble has been everywhere lately, and top tech companies like Google, Meta, and Microsoft have doubled down on their AI investments for 2026. But how have analysts in the past accurately identified forming tech bubbles? Hosts Michael Calore and Lauren Goode sit down with Brian Merchant, WIRED contributor and author of the newsletter to break down the four criteria some researchers have used in the past to understand and brace for the worst.

Hey Lauren, how are you doing? It's earnings season, so a lot of us on the business desk here at WIRED have been tuning into tech companies earnings reports and their earnings calls. And I guess that basically means it's CapEx season. Now that I'm a business desk reporter, I say CapEx. I throw it around at parties. But we are seeing a trend in how tech companies are sleeping on piles of money, but they aren't just sleeping on it. They're sharing big plans to spend on it, and especially to spend on AI infrastructure. And this is all partly what is fueling all of this talk about a bubble, which we touched on a little bit a couple of weeks ago with our colleague Molly Taft.

Next-gen networking tech, sometimes powered by light instead of electricity, is emerging as a critical piece of AI infrastructure. The new era of Silicon Valley runs on networking--and not the kind you find on LinkedIn. As the tech industry funnels billions into AI data centers, chip makers both big and small are ramping up innovation around the technology that connects chips to other chips, and server racks to other server racks. Networking technology has been around since the dawn of the computer, critically connecting mainframes so they can share data. In the world of semiconductors, networking plays a part at almost every level of the stack--from the interconnect between transistors on the chip itself, to the external connections made between boxes or racks of chips.

Nvidia's sophisticated chips have been an important part of the AI boom. On Wednesday it said demand for its products remains strong, especially from big tech firms including Instagram-owner Meta, and ChatGPT-maker OpenAI, as they race to build-out AI. "The AI race is now on," said Nvidia boss Jensen Huang in a call with analysts following the report's release, saying spending from four big tech firms had doubled to 600bn per year. "Over time, you would think that artificial intelligence would... accelerate GDP growth," Huang said. "Our contribution to that is a large part of the AI infrastructure." Colleen McHugh, chief investment officer at investment firm Wealthify, told the BBC's Today programme Nvidia was "at the heart of this AI boom".

Chip giant Nvidia has set a new sales record, a sign that demand for artificial intelligence remains strong despite fearsthe technology may be overhyped. Nvidia, the world's most valuable company, on Wednesday reported revenue of 46.74bn for the three months that ended in July, a rise of 56 percent year-on-year. Profit for the quarter was 26.42bn, a yearly rise of 59 percent. Nvidia's latest earnings report had been hotly anticipated as the tech giant is widely seen as a barometer of the AI boom, which has lifted the US stock market from all-time high to all-time high. Nvidia CEO Jensen Huang said that production of Blackwell Ultra, Nvidia's latest platform using its most advanced chips, was ramping up "at full speed" and demand for the company's products was "extraordinary".
