In today’s tech news roundup, several major developments highlight how artificial intelligence, cloud infrastructure, and startup innovation continue to reshape the global technology landscape.

Microsoft CEO Satya Nadella announced that Azure has become the first cloud provider to bring up NVIDIA’s Vera Rubin NVL72 system for validation. The new architecture is designed to power the next generation of AI infrastructure, promising significantly higher inference performance and lower cost per token compared to previous AI chips. This milestone strengthens Microsoft’s collaboration with Nvidia as both companies continue building advanced AI supercomputing capabilities for the cloud.

Meanwhile, WhatsApp is reportedly working on a new feature called Guest Chats that would allow users to communicate with people who do not have a WhatsApp account. The feature works through a secure chat link that opens in a browser, letting guests join a conversation temporarily without installing the app. However, the feature will initially support only text messages and will exclude calls, media sharing, and group chats.

OpenAI Chairman Bret Taylor also shared an interesting perspective on how artificial intelligence is changing software development. Speaking on a podcast, Taylor said it is emotionally difficult for developers to stop writing code themselves as AI tools increasingly generate and debug programs automatically. As AI capabilities grow, the role of engineers may shift from writing code to designing systems and guiding AI tools.

In another AI development, IIT Bombay graduate Devendra Singh Chaplot has joined Elon Musk’s AI startup xAI to help build superintelligence systems. Chaplot has previously worked with leading AI organizations including Meta AI, Mistral AI, and Thinking Machines Labs, and will now collaborate directly with Musk on advanced AI research.

Finally, the AI startup ecosystem has produced a new record-breaking entrepreneur. Surya Midha, the co-founder of AI recruitment platform Mercor, has become the world’s youngest self-made billionaire at just 22 years old. The company’s AI-powered hiring platform recently reached a valuation of around $10 billion, reflecting the explosive growth of artificial intelligence startups globally.

From AI infrastructure and cloud computing to startups and developer tools, these stories show how rapidly the global technology ecosystem continues to evolve.
