X CEO Yaccarino resigns as AI controversy and Musk’s influence grow

Linda Yaccarino has stepped down as CEO of X, ending a turbulent two-year tenure marked by Musk’s controversial leadership and ongoing transformation of the social media company.

Her resignation came just one day after a backlash over offensive posts by Grok, the AI chatbot created by Musk’s xAI, which had been recently integrated into the platform.

Yaccarino, who was previously a top advertising executive at NBCUniversal, was brought on in 2023 to help stabilise the company following Musk’s $44bn acquisition.

In her farewell post, she cited efforts to improve user safety and rebuild advertiser trust, but did not provide a clear reason for her departure.

Analysts suggest growing tensions with Musk’s management style, particularly around AI moderation, may have prompted the move.

Her exit adds to the mounting challenges facing Musk’s empire.

Tesla is suffering from slumping sales and executive departures, while X remains under pressure from heavy debts and legal battles with advertisers.

Yaccarino had spearheaded ambitious initiatives, including payment partnerships with Visa and plans for an X-branded credit or debit card.

Despite these developments, X continues to face scrutiny for its rightward political shift and reliance on controversial AI tools.

Whether the company can fulfil Musk’s vision of becoming an ‘everything app’ without Yaccarino remains to be seen.

Nvidia nears $4 trillion milestone as AI boom continues

Nvidia has made financial history by nearly reaching a $4 trillion market valuation, a milestone highlighting investor confidence in AI as a powerful economic force.

Shares briefly peaked at $164.42 before closing slightly lower at $162.88, just under the record threshold. The rise underscores Nvidia’s position as the leading supplier of AI chips amid soaring demand from major tech firms.

Led by CEO Jensen Huang, the company now holds a market value larger than the economies of Britain, France, or India.

Nvidia’s growth has helped lift the Nasdaq to new highs, aided in part by improved market sentiment following Donald Trump’s softened stance on tariffs.

However, trade barriers with China continue to pose risks, including export restrictions that cost Nvidia $4.5 billion in the first quarter of 2025.

Despite those challenges, Nvidia secured a major AI infrastructure deal in Saudi Arabia during Trump’s visit in May. Innovations such as the next-generation Blackwell GPUs and ‘real-time digital twins’ have helped maintain investor confidence.

The company’s stock has risen over 21% in 2025, far outpacing the Nasdaq’s 6.7% gain. Nvidia chips are also being used by the US administration as leverage in global tech diplomacy.

While competition from Chinese AI firms like DeepSeek briefly knocked $600 billion off Nvidia’s valuation, Huang views rivalry as essential to progress. With the growing demand for complex reasoning models and AI agents, Nvidia remains at the forefront.

Still, the fast pace of AI adoption raises concerns about job displacement, with firms like Ford and JPMorgan already reporting workforce impacts.

Quantum leap in Finland pushes qubit to millisecond range

Researchers in Finland have achieved a significant leap in quantum computing by extending qubit coherence to nearly one millisecond. The team at Aalto University and the VTT Technical Research Centre reported their success in Nature Communications, marking a new record for superconducting transmon qubits.

Coherence time, the duration a quantum bit maintains its state, is crucial for quantum computing. The Finnish transmon qubit reached an echo dephasing time of 1.057 milliseconds and a median energy relaxation time of 425 microseconds, far surpassing typical values.

Such improvements reduce error rates and boost the reliability of quantum operations, paving the way for more scalable and efficient quantum processors. Researchers also shared full details of their fabrication and measurement methods to ensure reproducibility and aid future development.

Due to this, Finland demonstrates its growing role in global quantum innovation, with strategic support from national and European institutions. Experts believe this progress will strengthen hopes of achieving fault-tolerant quantum computing shortly.

AI interviews leave job candidates in the dark

An increasing number of startups are now using AI to conduct video job interviews, often without making this clear to applicants. Senior software developers are finding themselves unknowingly engaging with automated systems instead of human recruiters.

Applicants are typically asked to submit videos responding to broad interview prompts, including examples and case studies, often without time constraints or human engagement.

AI processes these asynchronous interviews, which evaluate responses using natural language processing, facial cues and tone to assign scores.

Critics argue that this approach shifts the burden of labour onto job seekers, while employers remain unaware of the hidden costs and flawed metrics. There is also concern about the erosion of dignity in hiring, with candidates treated as data points rather than individuals.

Although AI offers potential efficiencies, the current implementation risks deepening dysfunctions in recruitment by prioritising speed over fairness, transparency and candidate experience. Until the technology is used more thoughtfully, experts advise job seekers to avoid such processes altogether.

AI industry warned of looming financial collapse

Despite widespread popularity and unprecedented investment, OpenAI may be facing a deepening financial crisis. Since launching ChatGPT, the company has lost billions yearly, including an estimated $5 billion in 2024 alone.

Tech critic Ed Zitron argues that the AI industry is heading towards a ‘subprime AI crisis’, comparing the sector’s inflated valuations and spiralling losses to the subprime mortgage collapse in 2007. Startups like OpenAI and Anthropic continue to operate at huge losses.

Companies relying on AI infrastructure are already feeling the squeeze. Anysphere, which uses Anthropic’s models, recently raised prices sharply, angering users and blaming costs passed down from its infrastructure provider.

To manage exploding demand, OpenAI has also introduced tiered pricing and restricted services for free users, raising concerns that access to AI tools will soon be locked behind expensive paywalls. With 800 million weekly users, any future revenue strategy could alienate a large part of its global base.

Zitron believes these conditions cannot sustain long-term growth and will ultimately damage revenues and public trust. The industry, he warns, may be building its future on unstable ground.

AI fluency is the new office software skill

As tools like ChatGPT, Copilot, and other generative AI systems become embedded in daily workflows, employers increasingly prioritise a new skill: AI fluency.

Much like proficiency in office software became essential in the past, knowing how to collaborate effectively with AI is now a growing requirement across industries.

But interacting with AI isn’t always intuitive. Many users encounter generic or unhelpful responses from chatbots and assume the technology is limited. In reality, AI systems rely heavily on the context they are given, and that’s where users come in.

Rather than considering AI as a search engine, it helps to see it as a partner needing guidance. A vague prompt like ‘write a proposal’ is unlikely to produce meaningful results. A better approach provides background, direction, and clear expectations.

One practical framework is CATS: context, angle, task, and style.

Context sets the stage. It includes your role, the situation, the audience, and constraints. For example, ‘I’m a nonprofit director writing a grant proposal for an environmental education program in urban schools’ offers much more to work with than a general request.

Angle defines the perspective. You can ask the AI to act as a peer reviewer, a mentor, or even a sceptical audience member. The roles help shape the tone and focus of the response.

Task clarifies the action you want. Instead of asking for help with a presentation, try ‘Suggest three ways to improve my opening slide for an audience of small business owners.’

Style determines the format and tone. Whether you need a formal report, a friendly email, or an outline in bullet points, specifying the style helps the AI deliver a more relevant output.

Beyond prompts, users can also practice context engineering—managing the environment around the prompt. The method includes uploading relevant documents, building on previous chats, or setting parameters through instructions. The steps help tailor responses more closely to your needs.

Think of prompting as a conversation, not a one-shot command. If the initial response isn’t ideal, clarify, refine, or build on it. Ask follow-up questions, adjust your instructions, or extract functional elements to develop further in a new thread.

That said, it’s essential to stay critical. AI systems can mimic natural conversation, but don’t truly understand the information they provide. Human oversight remains crucial. Always verify outputs, especially in professional or high-stakes contexts.

Ultimately, AI tools are powerful collaborators—but only when paired with clear guidance and human judgment. Provide the correct input, and you’ll often find the output exceeds expectations.

Sam Altman shrugs off Meta poaching, backs Trump, jabs at Musk

OpenAI CEO Sam Altman addressed multiple hot topics during the Sun Valley conference, including Meta’s aggressive recruitment of top AI researchers, his strained relationship with Elon Musk, and a surprising show of support for Donald Trump.

Altman downplayed Meta’s talent raids, saying he had not spoken to Mark Zuckerberg since the Meta CEO lured away three OpenAI researchers with a $100 million signing bonus. All three had worked at OpenAI’s Zurich office, which opened in 2024.

Despite the losses, Altman described the situation as ‘fine’ and ‘good’, suggesting OpenAI’s mission continues to retain top talent.

The OpenAI chief also took a subtle swipe at Meta’s smartglasses, saying he doesn’t like wearable tech and implying his company has no plans to follow suit.

On the topic of Elon Musk, Altman laughed off their rivalry, saying only that Musk’s bust-ups with everybody, and hinting at the long-running tension between the two former co-founders.

Perhaps most notably, Altman expressed disillusionment with the Democratic Party, saying he no longer feels represented by mainstream figures he once supported.

He praised Donald Trump’s focus on AI infrastructure. He even donated $1 million to Trump’s inaugural fund — a gesture reflecting a broader shift among Silicon Valley leaders warming to Trump as his popularity rises.

AI model detects infections from wound photos

Mayo Clinic researchers have developed an AI system capable of detecting surgical site infections from wound photographs submitted by patients. The model was trained using over 20,000 images from more than 6,000 persons across nine hospital locations.

The AI pipeline identifies whether a photo contains a surgical incision and then evaluates that incision for infection. Known as Vision Transformer, the model accurately recognises incisions and scores high in AUC in infection detection.

Medical staff review outpatient wound images manually, which can delay care and burden resources. Automating this process may improve early diagnosis, reduce unnecessary visits, and speed up responses to high-risk cases.

Researchers believe the tool could eventually serve as a frontline screening method, especially helpful in rural or understaffed areas. Consistent performance across diverse patient groups also suggests a lower risk of algorithmic bias, though further validation remains essential.

How agentic AI is transforming cybersecurity

Cybersecurity is gaining a new teammate—one that never sleeps and acts independently. Agentic AI doesn’t wait for instructions. It detects threats, investigates, and responds in real-time. This new class of AI is beginning to change the way we approach cyber defence.

Unlike traditional AI systems, Agentic AI operates with autonomy. It sets objectives, adapts to environments, and self-corrects without waiting for human input. In cybersecurity, this means instant detection and response, beyond simple automation.

With networks more complex than ever, security teams are stretched thin. Agentic AI offers relief by executing actions like isolating compromised systems or rewriting firewall rules. This technology promises to ease alert fatigue and keep up with evasive threats.

A 2025 Deloitte report says 25% of GenAI-using firms will pilot Agentic AI this year. SailPoint found that 98% of organisations will expand AI agent use in the next 12 months. But rapid adoption also raises concern—96% of tech workers see AI agents as security risks.

The integration of AI agents is expanding to cloud, endpoints, and even physical security. Yet with new power comes new vulnerabilities—from adversaries mimicking AI behaviour to the risk of excessive automation without human checks.

Key challenges include ethical bias, unpredictable errors, and uncertain regulation. In sectors like healthcare and finance, oversight and governance must keep pace. The solution lies in balanced control and continuous human-AI collaboration.

Cybersecurity careers are shifting in response. Hybrid roles such as AI Security Analysts and Threat Intelligence Automation Architects are emerging. To stay relevant, professionals must bridge AI knowledge with security architecture.

Agentic AI is redefining cybersecurity. It boosts speed and intelligence but demands new skills and strong leadership. Adaptation is essential for those who wish to thrive in tomorrow’s AI-driven security landscape.
