Google Messages now blurs nudity by default with on-device AI
The safety system also intervenes before users attempt to send or forward potentially explicit images. If such content is detected, Google Messages will prompt the sender with a confirmation step: "Yes, send" or "No, don't send." The idea isn't to block actions entirely but to introduce a thoughtful pause — a "speed bump" — to encourage users to reconsider impulsive decisions.As of now, the feature is limited to image-based content and does not apply to videos. It also works only when the image is shared through Google Messages with sensitive content warnings turned on. Other apps must explicitly integrate with SafetyCore for similar protection.Though the feature was officially announced in October and began rolling out in phases from February, its availability remains limited. According to early tests, the setting — located under Messages > Protection & Safety > Manage sensitive content warnings — has only appeared on a few beta devices so far, suggesting a broader rollout is still in progress.

The future of learning: AI that makes students think harder, not less
For years, educators have watched with growing concern as Artificial Intelligence tools like ChatGPT has transformed student behaviour in ways that seemed to undermine the very essence of learning. Students began copying and pasting AI responses, submitting machine-generated essays, and bypassing the mental effort that builds genuine understanding. But a quiet revolution is now underway in classrooms around the world—one that promises to transform AI from an academic shortcut into a powerful thinking partner. The crisis of instant answers The numbers tell a troubling story. A 2023 survey revealed that 30% of college students admitted to using AI to complete work they didn't fully understand, highlighting a critical disconnect between AI assistance and genuine learning. The problem isn't AI's presence in education—it's how these tools have been designed. Educational experts observe that most AI tools entering classrooms today are optimized for output rather than learning. These systems excel at generating essays, solving complex problems, and providing comprehensive explanations—capabilities that inadvertently encourage academic shortcuts. Traditional AI operates as sophisticated answer engines, designed to be helpful by providing immediate solutions. While this approach serves many purposes in professional settings, it fundamentally misaligns with educational goals. Learning requires struggle, reflection, and the gradual construction of understanding—processes that instant answers can circumvent entirely. The Socratic solution The answer lies in reimagining AI as a Socratic partner rather than an oracle. This revolutionary approach, exemplified by innovations such as Claude's Learning Mode, GPT-4's enhanced reasoning capabilities, and Google's Bard educational features, along with similar tools being developed across the education technology sector, transforms AI from a source of answers into a facilitator of inquiry. Instead of responding to 'What caused the 2008 financial crisis?' with a comprehensive explanation, a Socratic AI might ask: 'What economic factors have you already considered?' or 'Which indicators do you think played the most significant role?' This approach extends beyond economics into other critical fields. In healthcare education, rather than immediately diagnosing a patient case study, AI might prompt: 'What symptoms are you prioritizing in your assessment?' or 'Which differential diagnoses have you ruled out and why?' In finance training, instead of providing investment recommendations, AI could ask: 'What risk factors are you weighing in this portfolio decision?' or 'How do current market conditions influence your analysis?' This method draws from centuries of educational theory. Socratic questioning has long been recognized as one of the most effective ways to develop critical thinking skills. By prompting learners to examine their assumptions, articulate their reasoning, and explore alternative perspectives, it builds the intellectual muscles that passive consumption cannot develop. Early adopters see promising result Several major institutions are already pioneering this approach with remarkable results. Northeastern University's deployment of AI across 13 campuses, affecting over 50,000 students and staff, demonstrates the scalability of thoughtful AI integration. The London School of Economics and Champlain College are similarly experimenting with AI tools that enhance rather than replace critical thinking. Researchers have found that when students use AI as a thinking partner rather than an answer source, they develop stronger foundational understanding before engaging with more complex classroom discussions. Educational institutions report that students arrive in class better prepared with more focused, sophisticated questions. These early implementations reveal several crucial success factors: Ethical boundaries: Effective educational AI must be programmed to refuse requests that undermine learning integrity. This isn't just content filtering—it requires AI systems designed with educational principles at their core. Faculty integration: Success requires AI tools that complement rather than replace instructors. The most effective implementations support teachers by helping students engage more meaningfully with course material. Student preparation: When properly introduced to these tools, students quickly adapt to using AI as a collaborative thinking partner rather than a homework completion service. The technology behind thinking Creating effective AI tools for critical thinking requires careful consideration of both technical and pedagogical factors. Educational AI is being built with what developers call a 'Constitutional AI Framework'—explicit ethical guidelines that prioritize learning over convenience, embedded in the model's core reasoning rather than added as superficial filters. These new systems feature adaptive questioning that adjusts based on student responses, becoming more sophisticated as learners demonstrate greater mastery. Multi-modal interaction capabilities support various learning preferences through text, voice, visual, and interactive elements, while strict privacy protections ensure student data remains secure. Implementation across levels The Socratic AI approach shows promise across different educational stages: K-12 Education: Elementary students engage with AI tools that ask simple 'why' and 'how' questions to build foundational inquiry skills. Middle schoolers work with more sophisticated questioning that introduces multiple perspectives and evidence evaluation. High school students use advanced critical thinking tools that support research, argumentation, and complex problem-solving. Higher education: Undergraduate programs use AI tools that facilitate deep learning in specific disciplines while maintaining academic integrity. Graduate students work with research-focused AI that helps develop original thinking and methodology. Professional schools employ AI tools that simulate real-world problem-solving scenarios and ethical decision-making. Corporate training: Leadership development programs use AI tools that challenge assumptions and facilitate strategic thinking. Technical training incorporates AI that guides learners through complex problem-solving processes. Compliance training features AI that helps employees think through ethical scenarios and regulatory requirements. Measuring success beyond test scores Traditional educational metrics—standardized test scores, grade point averages, and completion rates—may not capture the full impact of AI tools designed for critical thinking. These conventional measures often emphasize knowledge retention and procedural skills rather than the deeper cognitive abilities that Socratic AI aims to develop. Instead, institutions are pioneering new assessment approaches that evaluate the quality of thinking itself, recognizing that the most important educational outcomes may be the least visible on traditional report cards. Depth of questioning: Educational researchers are tracking whether students' progress from surface-level inquiries to more sophisticated, multi-layered questions that demonstrate genuine curiosity and analytical thinking. Rather than asking 'What happened?' students begin posing questions like 'What factors contributed to this outcome, and how might different circumstances have led to alternative results?' Assessment tools now measure question complexity, the frequency of follow-up inquiries, and students' ability to identify what they don't yet understand. Advanced AI systems can analyse the sophistication of student questions in real-time, providing educators with insights into developing intellectual curiosity that traditional testing cannot reveal. Argumentation quality: Modern assessment focuses on students' ability to construct well-reasoned arguments supported by credible evidence, acknowledge counterarguments, and build logical connections between premises and conclusions. Evaluators examine whether students can distinguish between correlation and causation, recognize bias in sources, and present balanced analyses of complex issues. New rubrics assess the strength of evidence selection, the logical flow of reasoning, and students' ability to anticipate and address potential objections to their positions. This approach values the process of building an argument as much as the final conclusion, recognizing that strong reasoning skills transfer across all academic and professional contexts. Transfer or learning: Perhaps the most crucial indicator of educational success is students' ability to apply critical thinking skills across different subjects, contexts, and real-world situations. Assessment tools now track whether a student who learns analytical techniques in history class can apply similar reasoning to scientific methodology, business case studies, or personal decision-making. Educators observe whether students recognize patterns and principles that span disciplines, such as understanding how statistical reasoning applies equally to social science research and medical diagnosis. This transfer capability indicates that students have internalized thinking processes rather than merely memorized subject-specific content. Metacognitive awareness: Advanced educational assessment now includes measures of students' consciousness about their own thinking processes—their ability to recognize when they're making assumptions, identify their own knowledge gaps, and select appropriate strategies for different types of problems. Students demonstrating strong metacognitive awareness can articulate their reasoning process, explain why they chose particular approaches, and self-assess the strength of their conclusions. They become skilled at asking themselves questions like 'What evidence would change my mind?' or 'What assumptions am I making that I should examine?' This self-awareness transforms students into independent learners capable of continuous intellectual growth. Intellectual humility: Modern assessment recognizes intellectual humility—the willingness to revise views when presented with compelling evidence—as a crucial indicator of educational maturity. Rather than rewarding students for defending initial positions regardless of new information, evaluation systems now value intellectual flexibility and evidence-based reasoning. Students demonstrating intellectual humility acknowledge the limits of their knowledge, seek out disconfirming evidence, and show genuine curiosity about alternative perspectives. They express confidence in their reasoning process while remaining open to new information that might refine or change their conclusions. Collaborative problem solving: New assessment approaches also evaluate students' ability to engage in productive collaborative thinking, building on others' ideas while contributing unique perspectives. These measures track whether students can synthesize diverse viewpoints, facilitate group inquiry, and help teams navigate disagreement constructively. Long-term impact tracking: Some institutions are implementing longitudinal studies that follow graduates to assess how AI-enhanced critical thinking education influences career success, civic engagement, and lifelong learning habits. These studies examine whether students who experienced Socratic AI education demonstrate superior problem-solving abilities, greater adaptability to changing professional demands, and more effective leadership skills in their post-graduation lives. Portfolio-based assessment: Rather than relying on isolated examinations, innovative institutions are developing portfolio systems that document students' thinking evolution over time. These portfolios include reflection essays, problem-solving process documentation, peer collaboration records, and evidence of intellectual growth across multiple contexts, providing a comprehensive picture of educational development that single assessments cannot capture. Challenges on the horizon The transformation faces significant hurdles. Technical challenges include developing AI capable of sophisticated educational dialogue while ensuring consistent ethical behaviour across diverse contexts. Creating tools that adapt to individual learning needs while maintaining privacy and security presents ongoing difficulties. Institutional challenges include faculty resistance to new technologies, concerns about AI replacing human instruction, budget constraints, and the need for comprehensive training systems. Students themselves may initially resist AI that doesn't provide immediate answers, requiring a learning curve to engage effectively with Socratic AI tools. The digital divide also poses concerns about equitable access to these advanced educational technologies. The future of AI-enhanced learning As AI tools become more sophisticated, several transformative developments are anticipated that will reshape the educational landscape: Personalised learning pathways: The next generation of AI will create unprecedented levels of educational customization. These systems will continuously analyse how individual students learn best, identifying optimal pacing, preferred explanation styles, and effective motivational approaches. For instance, a student struggling with mathematical concepts might receive visual representations and real-world applications, while another excels with abstract theoretical frameworks. AI will also map knowledge gaps in real-time, creating adaptive learning sequences that address weaknesses while building on strengths. This personalization extends beyond academic content to include emotional and social learning, with AI recognizing when students need encouragement, challenge, or different types of support. Cross-curricular integration: Future AI systems will excel at helping students discover connections between seemingly unrelated subjects, fostering the interdisciplinary thinking essential for solving complex modern problems. Students studying climate change, for example, will be guided to see connections between chemistry, economics, political science, and ethics. AI will prompt questions like 'How might the economic principles you learned in your business class apply to environmental policy?' or 'What historical patterns can inform our understanding of social responses to scientific challenges?' This approach mirrors how real-world problems require integrated knowledge from multiple disciplines, better preparing students for careers that demand versatile thinking. Real-world problem solving: AI will increasingly facilitate engagement with authentic, complex challenges that mirror those professionals face in their careers. Rather than working with simplified textbook problems, students will tackle genuine issues like urban planning dilemmas, public health crises, or technological implementation challenges. AI will guide students through the messy, non-linear process of real problem-solving, helping them navigate ambiguity, consider multiple stakeholders, and develop practical solutions. These experiences will develop not just critical thinking skills, but also resilience, creativity, and the ability to work with incomplete information—capabilities essential for success in rapidly changing careers. Global collaboration: AI tools will break down geographical and cultural barriers, enabling students from different countries and educational systems to collaborate on shared learning experiences. These platforms will facilitate cross-cultural dialogue while helping students understand different perspectives on global issues. AI will serve as a cultural translator and mediator, helping students from diverse backgrounds communicate effectively and learn from their differences. Virtual exchange programs powered by AI will allow students to engage in joint research projects, debate global challenges, and develop the international competency increasingly valued in the modern workforce. Adapting assessment and feedback: Future AI systems will revolutionize how learning is assessed, moving beyond traditional testing to continuous, contextual evaluation. These tools will observe student thinking processes during problem-solving, providing insights into reasoning patterns, misconceptions, and growth areas. Assessment will become a learning opportunity itself, with AI offering immediate, specific feedback that guides improvement rather than simply measuring performance. Emotional intelligence development: Advanced AI will recognize and respond to students' emotional states, helping develop crucial soft skills alongside academic knowledge. These systems will guide students through collaborative exercises, conflict resolution, and empathy-building activities, preparing them for leadership roles in increasingly complex social environments. Lifelong learning support: As careers become more dynamic and require continuous skill updating, AI learning partners will evolve alongside learners throughout their professional lives. These systems will help professionals identify emerging skill needs, design learning paths for career transitions, and maintain intellectual curiosity across decades of changing work environments. A pedagogical revolution The transformation of AI from answer engine to thinking partner represents more than a technological shift—it's a pedagogical revolution. In an era where information is abundant but understanding is scarce, AI tools that prioritize depth over speed may be essential for developing the critical thinking skills students need for success in an increasingly complex world. Educational technology leaders note that institutions are at a critical juncture in AI implementation. The early success of Socratic AI implementations demonstrates that technology can enhance rather than undermine educational goals when designed with learning principles at its core. As more institutions experiment with these approaches, AI is poised to become an indispensable partner in developing the critical thinking skills that define educated, engaged citizens. The challenge now is to scale these innovations thoughtfully, ensuring that AI tools remain true to their educational mission while becoming accessible to learners across all contexts. The journey from AI as a shortcut to AI as a thinking partner is just beginning. For educators, technologists, and policymakers, the opportunity to shape this transformation represents one of the most important challenges—and opportunities—of our time. The future of education may well depend on our ability to develop AI that makes students think harder, not less. This article is based on research and implementations from leading educational institutions including Northeastern University, the London School of Economics, and Champlain College, as well as analysis of emerging AI tools in classroom settings and educational technology research.

Aravind Srinivas-led Perplexity's $34.5bn Chrome bid: Are browsers the next AI battleground?
The surprise $34.5 billion offer from artificial intelligence start-up Perplexity to buy Google's Chrome browser may or may not be a long shot, but it points to a far bigger shift in the tech landscape: the internet browser is fast becoming the new battleground for AI dominance. Chrome, used by an estimated 3.5 billion people worldwide, is not just a gateway to the web; it is increasingly a prime channel for shaping how users interact with technology. While the browser's role has traditionally been to connect people to search engines, AI firms now see it as a direct on-ramp to their own services, bypassing search altogether. Perplexity has already dipped its toes into this territory with Comet, its own experimental browser that places an AI assistant at the heart of the experience. Queries typed into its address bar are answered by AI rather than through a conventional web search. For now, Comet's reach is negligible compared with Chrome's market share of more than two-thirds on both desktop and mobile, but an acquisition could change that overnight. The potential transformation is clear: if an AI-driven browser became the default for billions of users, it could reset entrenched habits around information-seeking and online discovery. Search engines and the advertising businesses built around them, would lose their dominance, replaced by AI models capable of delivering tailored answers instantly. This is why Perplexity's bid, however improbable, carries symbolic weight. It challenges Google's assertion in its antitrust defence that Chrome would wither if separated from the company, while also revealing the stakes for the AI sector. Competitors understand that owning the user's entry point to the internet could prove decisive in the coming years. A Bloomberg report notes that Chrome's true value may be far higher than Perplexity's proposed price, with estimates stretching to $100 billion. But even without a realistic path to acquisition, the move signals that browsers, long considered stable, almost commoditised software, are now strategic assets in the race to own the future of online interaction.
