OpenAI’s chief people officer, Julia Villagra, has left the company, marking the latest leadership change at the AI pioneer. Villagra, who joined the San Francisco firm in early 2024 and was promoted in March, previously led its human resources operations.
Her responsibilities will temporarily be overseen by chief strategy officer Jason Kwon, while chief applications officer Fidji Simo will lead the search for her successor.
OpenAI said Villagra is stepping away to pursue her personal interest in art, music and storytelling as tools to help people understand the shift towards artificial general intelligence, a stage when machines surpass human performance in most forms of work.
The departure comes as OpenAI navigates a period of intense competition for AI expertise. Microsoft-backed OpenAI is valued at about $300 billion, with a potential share sale set to raise that figure to $500 billion.
The company faces growing rivalry from Meta, where Mark Zuckerberg has reportedly offered $100 million signing bonuses to attract OpenAI talent.
While OpenAI expands, public concerns over the impact of AI on employment continue. A Reuters/Ipsos poll found 71% of Americans fear AI could permanently displace too many workers, despite the unemployment rate standing at 4.2% in July.

A controversial study that once claimed evidence of elusive Majorana quasiparticles has received a 20-page correction in Science five years after its publication.
The paper, led by researchers in Copenhagen and affiliated with Microsoft, originally described signals from nanowires that were said to match those expected from Majoranas, exotic entities believed to be useful for quantum computing due to their resistance to noise.
Independent investigators concluded that, although the data selection was narrow, no misconduct occurred. The omitted data did not invalidate the main claims, but raised concerns about transparency and selection bias in reporting.
The authors argue the correction merely clarifies their methods. Yet the wider research community remains divided, and no group has successfully replicated the findings. Some experts now see the approach as too fragile for practical use in quantum computing.

Google has introduced a new version of its Gemini AI platform tailored specifically for US government use, called Gemini for Government. The platform combines features such as image generation, enterprise search, and AI agent development, with compliance to standards like Sec4 and FedRAMP.
Gemini includes pre-built AI agents for research and idea generation, while also offering tools to create custom agents. US government customers will pay $0.50 per year for basic access, undercutting rivals OpenAI and Anthropic, who each launched $1 government-focused AI packages earlier this year.
Google emphasised security, privacy, and automation in its pitch, positioning the product as an all-in-one solution for public sector institutions. The launch follows the Trump administration’s AI Action Plan, which seeks to promote AI growth.

South Korea’s new administration has unveiled a five-year economic plan to build what it calls a ‘super-innovation economy’ by integrating AI across all sectors of society.
The strategy, led by President Lee Jae-myung, commits 100 trillion won (approximately US$71.5 billion) to position the country among the world’s top three AI powerhouses. Private firms will drive development, with government support for nationwide adoption.
Plans include a sovereign Korean-language AI model, humanoid robots for logistics and industry, and commercialising autonomous vehicles by 2027. Unmanned ships are targeted for completion by 2030, alongside widespread use of drones in firefighting and aviation.
AI will also be introduced into drug approvals, smart factories, welfare services, and tax administration, with AI-based tax consultations expected by 2026. Education initiatives and a national AI training data cluster will nurture talent and accelerate innovation.
Five domestic firms, including Naver Cloud, SK Telecom, and LG AI Research, will receive state support to build homegrown AI foundation models. Industry reports currently rank South Korea between sixth and 10th in global AI competitiveness.

AI-enabled cameras in Devon and Cornwall have detected 6,000 people failing to wear seat belts over the past year. The number caught was 50 percent higher than those penalised for using mobile phones while driving, police confirmed.
Road safety experts warn that the long-standing culture of belting up may be fading among newer generations of drivers. Geoff Collins of Acusensus noted a rise in non-compliance and said stronger legal penalties could help reverse the trend.
Current UK law imposes a £100 fine for not wearing a seat belt, with no points added to a driver’s licence. Campaigners now urge the government to make such offences endorsable, potentially adding penalty points and risking licence loss.

College students are increasingly turning to AI chatbots for emotional support, prompting concern among mental health professionals. A 2025 report ranked ‘therapy and companionship’ as the top use case for generative AI, particularly among younger users.
Studies by MIT and OpenAI show that frequent AI use can lower social confidence and increase avoidance of face-to-face interaction. On campuses, digital mental health platforms now supplement counselling services, offering tools that identify at-risk students and provide basic support.
Experts warn that chatbot companionship may create emotional habits that lack grounding in reality and hinder social skill development. Counsellors advocate for educating students on safe AI use and suggest universities adopt tools that flag risky engagement patterns.

US tech stocks have stumbled after a sharp rally, with investors increasingly cautious over AI-linked valuations and shifting market conditions. The S&P 500 tech sector has dropped around 2.5% this week, while the Nasdaq has slipped 2%, led by losses in Nvidia and Palantir.
The fall follows a 50% surge in tech shares since April, far outpacing the broader market and pushing valuations to year-highs. Concerns are growing that investor enthusiasm around AI has become overheated, with some funds reducing their exposure ahead of expected interest rate guidance.
US market watchers are now focused on Federal Reserve Chair Jerome Powell’s speech at Jackson Hole, which could signal if rate cuts are on the horizon. Tech stocks, already heavily weighted in many portfolios, are particularly vulnerable to higher rates due to their stretched price-to-earnings ratios.

Japan has pledged $5.5 billion in loans and announced an ambitious AI training programme to deepen economic ties with Africa.
At TICAD 9, Prime Minister Shigeru Ishiba proposed creating an Indian Ocean–Africa economic zone to link African nations with Asia and the Middle East.
Japan will also support training 30,000 AI experts over three years to drive digital transformation and job growth across the continent.
The initiative comes amid growing calls from leaders like António Guterres and João Lourenço to overhaul global finance systems and empower African representation.
Japan’s move signals renewed interest in African engagement, as the US scales back and China’s influence expands across the region.

Honda has entered a multiyear partnership with US-based startup Helm.ai to enhance self-driving systems in its vehicles.
The collaboration focuses on developing advanced driver assistance for Honda’s mass market range, with a target launch set for 2027.
Helm.ai, backed by over $100 million in funding, specialises in AI camera-based perception software and simulation technologies.
Honda has held an equity stake in the firm since 2021, having invested at least $30 million to support early-stage development.
The move places Honda among major global carmakers aiming to deliver partial automation on highways and regular roads. Existing systems like GM’s SuperCruise and Tesla’s Autopilot have already pushed ahead in the driver assistance space.
