South Korean chip giant SK Hynix has raised a record-breaking $26.5bn ahead of its Wall Street debut amid soaring demand for semiconductors used in AI. SK Hynix said on Friday that it had sold 177.9 million American depositary shares (ADS) at $149 each ahead of its listing on the New York-based Nasdaq stock exchange. SK Hynix's 177.9 million ADSs are equivalent to 18 million ordinary shares. SK Hynix's initial public offering (IPO) marks the largest-ever listing by a foreign company in the US, surpassing Chinese e-commerce giant Alibaba's $25bn debut in 2014. The listing also ranks as the second-largest globally, after SpaceX's record-breaking $85.7bn Nasdaq listing in June.

Amid live coding sessions and Silicon Valley optimism, the UN's AI for Good summit wrestled with an increasingly urgent question: Can global governance catch up before the technology races beyond its control? Dodge past the live onstage coding sessions, AI refresher courses, an obstacle course of gizmos, round people walking round with glowing green silent-disco-style headphones blaring UN panel discussions into your ears, and you can take a pause for breath. But you might find yourself in the Networking Zone, on a rotating seating contraption called UFOTECH that looks more like the kind of lazy Susan you'd encounter at a Chinese restaurant than the networking bench it is designed to function as. This is the AI for Good summit, organized by the United Nations' International Telecommunication Union (ITU), where representatives from the private and public sectors try to discuss how to harness the technology for the benefit, rather than the detriment, of humanity. While Silicon Valley execs and AI lab leaders are testifying to lawmakers in Washington about the risks of superintelligence, and the White House slaps export controls on chips, the UN AI for Good Summit--now in its 10th year--is focused on much more idealistic goals.

AI has prompted fears over job security for City workers, particularly staff that do back-office work. AI has prompted fears over job security for City workers, particularly staff that do back-office work. Reeves to launch City'skills compact' committing firms to retrain staff in AI Chancellor Rachel Reeves is to announce a new City "skills compact" that will commit firms such as Barclays and Lloyds to retraining thousands of financial sector workers for the AI revolution. The financial services skills compact will be launched on Tuesday, during what is likely to be Reeves's final Mansion House speech to City bosses before Andy Burnham's expected takeover of No 10. The government-backed initiative will commit employers to improving workers' skills and helping them "keep pace" with significant technological changes that have prompted fears of mass redundancies.

Headlong's take on Karel Čapek's 1920 tale of romance and robots is rife with timely debates about tech's threat but at times the philosophical discussions drag on I f our world is currently thinking through the brave new future of generative AI and super intelligence, Karel Čapek's 1920 play RUR: Rossum's Universal Robots proves the notion of robot consciousness and rebellion is not a new anxiety. So does Mary Shelley's Frankenstein, which Čapek's drama resembles in its philosophical debates and moral warnings, despite its futurism. Ella Road adapts Čapek's play for our times in this Headlong and Schwarzman Centre co-production, its science apparently informed by research from Oxford University academics, which gives it a cutting-edge, real-world underpinning. The stage is presented as the operations office for the company, also named RUR, which is creating humanoids by mixing human flesh and blood with code and data at its headquarters on an island (a lovely, lush foliage and scaffold design by Loren Elstein). Dom (Trevor Fox) is the company's boss - a "dom" in more ways than one as he is having a Secretary-style, S&M romance with his robot personal assistant, Sulla (Tiffany Gray).

South Korean computer chip maker SK Hynix has raised $26.5bn (£19.8bn) in its New York share offering, marking the largest ever listing by a foreign firm in the US. The company, a key supplier to artificial intelligence (AI) chip giant Nvidia, said on Thursday that it had sold 177.9 million American depositary shares for $149 each. The shares are set to begin trading on Friday on the Nasdaq. In May, SK Hynix saw its market value top $1tn in its home country, lifted by the boom in demand for AI chips. Its share price has more than tripled in South Korea this year, which along with Samsung Electronics has helped boost the benchmark Kospi index by more than 70% over the same period.

Smoke rises from an oil refinery following a Ukrainian drone attack on Moscow last month. Kremlin insiders say recent Ukrainian strikes have strengthened Russian President Vladimir Putin's resolve to keep fighting. Russian President Vladimir Putin is rejecting calls to negotiate peace with Kyiv, three sources close to the Kremlin said, with Ukraine's recent drone strikes on Russia's oil refineries and ports strengthening his resolve to keep fighting for now. Two of the sources, speaking on condition of anonymity, said that Putin was instead likely to escalate the conflict, now well into its fifth year. One of them, who meets regularly with the president, described a "high probability" of escalation in the coming months.

PCWorld explores strategic AI delegation, emphasizing three key questions to determine which tasks are appropriate for AI assistance versus human decision-making. The guide matters for productivity-focused users seeking to leverage AI chatbots like ChatGPT, Claude, and Gemini for tedious data compilation and repetitive tasks while avoiding over-reliance. Key recommendations include delegating boring, repeatable tasks like email management and voice memo transcription to AI, but retaining all final decision-making authority for yourself. You know what's harder than making decisions?

The move comes after Simo took significant medical leave. She will stay on as a part-time adviser. OpenAI's chief executive of AGI deployment, Fidji Simo, is leaving her full-time role at the company and transitioning to become a part-time adviser. The move comes after Simo took a monthslong medical leave due to a worsening neuroimmune condition. "Three months ago, I had to go on medical leave after a severe exacerbation of a chronic illness I've lived with for seven years," Simo wrote in a post Thursday on X. "During that time, it became clear that the road to recovery would be much longer and more complex than I had anticipated--and that I needed to focus on it fully."
