The new AI model Claude Mythos shows how technology can now find and exploit weaknesses in computer systems faster than humans. This power can help protect networks but also create new risks if misused. Governments and companies must act quickly to set fair rules and share responsibility. Cybersecurity is no longer just about fixing problems — it is about managing power wisely. Mythos reminds us that progress must come with caution, because the same intelligence that builds safety can also break it if left unchecked.K Chidanand KumarBengaluruEthanol transition pathThis refers to ‘Centre pushes for 100% ethanol-powered vehicles’ (April 29). Building on E20’s success, the move towards E100 signals a clear step towards energy independence. However, higher ethanol blends reduce fuel efficiency and may raise running costs. Feedstock expansion must be managed without straining land and food needs. This calls for closer alignment between policy ambition and field readiness. A phased rollout, supported by stable supply chains and transparent pricing, can ease the transition.S BalasubramaniyanVillupuram, TNMillet consumptionApropos ‘Millets are still not on our menu’’ (April 30), it is really disheartening to learn that consumption of millets, which are rich in iron, calcium, fibre and so on, is falling despite India accounting for nearly 38 per cent of global output of the commodity. Once people develop a habit of consuming millets (like how they have for rice, wheat, etc), then it will become permanent item on their menu.S RamakrishnasayeeChennaiDeciphering rupee’s fallThis refers to ‘Why the rupee has fallen steeply’ (April 30). The authors make a persuasive case that the rupee’s sharp fall was driven less by weak fundamentals and more by sentiment-driven capital flows. The self-fulfilling nature of depreciation expectations is a genuine concern, and the RBI’s intervention appears justified on those grounds. That said, the deeper structural issue deserves attention: India’s relative shortage of AI-related stocks and slower corporate earnings growth made it a less attractive destination when global capital grew cautious. Addressing that gap is a medium-term imperative that monetary intervention alone cannot substitute for.M BarathiBengaluruPublished on April 30, 2026Sign into Unlock benefits!Access 10 free stories per monthAccess to comment on every storySign up/Manage to our newslettersGet notified by email for early preview to new features, discounts & offers${ ind + 1 } ${ device }Last active - ${ la }
