'In the long term, space-based AI is obviously the only way to scale,' Musk wrote in a memo announcing that SpaceX would acquire his AI company, xAI,earlier this month. SpaceX says its goal is to launch a 'constellation of a million satellites that operate as orbital data centers,' and it's now hiring to make it happen. Each will generate about 100 kW of compute power per ton and would add 100 gigawatts of AI compute capacity annually, the company says.

And now, Nvidia is the largest suppler by a long shot of chips for artificial intelligence. Its GPUs have proven to be the best option for training and running AI models. Developers from OpenAI to Google, Anthropic, Meta and Amazon, along with a host of specialized startups, are fighting to get their hands on Nvidia chips. That high demand has made the manufacturer the most valuable company in the world.

Naver reported 2025 revenue of 12.35 trillion won ($9.15 billion) and operating profit of 2.21 trillion won ($1.64 billion), up 12.1% and 11.6%, respectively, from a year earlier, during its fourth-quarter earnings call. Fourth-quarter revenue rose 10.7% to 3.20 trillion won ($2.37 billion), while operating profit increased 12.7% to 610.6 billion won ($453 million), lifting the operating margin to 19.1%.

Somewhere between six and seven million years ago, our ancestors began walking upright, and the advantages were considerable: Freed from locomotion, upper limbs could grasp, manipulate, eventually craft, and the opposable thumb became the hinge on which human civilization would turn. We are, above all else, tool users-fire, the wheel, writing, the printing press, the transistor-each tool reshaping not only what we could do but who we became.

The Microsoft AI CEO said in an episode of the "Exponential View" podcast published Thursday that AI tools now make it possible for anyone to quickly start launching code and apps. "It is so accessible now," said Suleyman. "You can watch a three-minute video, get spun up, launch one of these things." "You can create an app, a web app in seconds," he added. Suleyman said people don't need deep technical skills to get started. Instead, they can learn by experimenting, watching, and doing.

Datadog recently announced that its LLM Observability platform now provides automatic instrumentation for applications built with Google's Agent Development Kit (ADK), offering deeper visibility into the behavior, performance, cost, and safety of AI-driven agentic systems. The integration, highlighted on the Google Cloud Blog, aims to make it easier for developers and SRE teams to monitor and troubleshoot complex multi-step AI agent workflows without extensive manual setup or custom instrumentation.

A small group of prominent tech companies had been handing money to each other for some time. The best summary was visual: Bloomberg clearly showed the circular flow of finances between Nvidia, AMD, Oracle, OpenAI, CoreWeave, and others. In the case of the Nvidia-OpenAI deal, the $100 billion investment would benefit new AI infrastructure, mostly filled with Nvidia hardware, which in turn would be paid for with that investment money.

Tools to create tailored, even personalised, scams leveraging, for example, deepfake videos of Swedish journalists or the president of Cyprus are no longer niche, but inexpensive and easy to deploy at scale, said the analysis from the AI Incident Database. It catalogued more than a dozen recent examples of impersonation for profit, including a deepfake video of Western Australia's premier, Robert Cook, hawking an investment scheme, and deepfake doctors promoting skin creams.

The human brain is complex. Artificial intelligence (AI) machine learning and medical imaging data are accelerating breakthroughs in brain health, especially in medical diagnostics. A peer-reviewed study published today in Nature Neuroscience unveils an AI foundation model called BrainIAC (Brain Imaging Adaptive Core) that is capable of predicting brain age, dementia, time-to-stroke, and brain cancer from brain magnetic resonance imaging (MRI).

Oracle's investments in AI may prove costly. Investment bank TD Cowen says the company hopes to reduce costs to finance its ambitious AI infrastructure build. To that end, it has already accumulated $58 billion in debt in two months. A round of layoffs affecting 30,000 employees is possible, while even a spin-off of Oracle Health, formerly Cerner, is being considered. Since September, Oracle has lost half of its market value, which currently stands at just under $400 billion.

Rival OpenAI sees it differently, and now plans to embed advertising in ChatGPT, something that CEO Sam Altman had previously said would be a "last resort". It's an indication that AI companies are still trying to balance the cost of development with the provision of service to their users.
