From Concrete to Compute

How SN Subrahmanyan Is Shaping L&T's AI Future For more than eight decades, Larsen & Toubro (L&T) has been synonymous with India's physical infrastructure, delivering metro systems, airports, power plants and some of the country's most complex engineering projects. Under L&T Chairman SN Subrahmanyan, however, the company's definition of infrastructure is expanding. Increasingly, it includes artificial intelligence, cloud computing, data centres and sovereign digital infrastructure the building blocks of India's next phase of economic growth. That shift came into sharp focus at the India AI Impact Summit 2026, where SN Subrahmanyan joined NVIDIA founder Jensen Huang to unveil a strategic collaboration aimed at accelerating AI infrastructure in India. The announcement reflected more than a technology partnership; it signalled L&T's ambition to evolve from a builder of physical assets into an enabler of the country's AI-powered future. An Engineer's Perspective on AI Unlike many business leaders who entered the AI conversation as the technology gained mainstream attention, SN Subrahmanyan approaches it through the lens of an engineer. A civil engineering graduate, he joined L&T in 1984 as a project planning engineer and spent four decades leading some of the company's largest infrastructure businesses across India and the Middle East, including projects such as the Riyadh Metro, Doha Metro and Salalah Airport. After serving as Chief Executive Officer and Managing Director from 2017, he became Chairman and Managing Director in 2023. That experience continues to shape his leadership philosophy. Rather than viewing AI as a standalone technology trend, Subrahmanyan sees it as an extension of engineering one that can improve planning, design, execution and operations at scale. During L&T's FY2024 Annual General Meeting, he described generative AI as a "game changer" and outlined how the company was embedding it across the project lifecycle to improve productivity and decision-making. Why L&T Is Investing in AI Infrastructure For L&T Chairman SN Subrahmanyan, AI is not only about adopting intelligent software; it is about building the infrastructure that makes large-scale AI deployment possible. Through its collaboration with NVIDIA, L&T plans to develop one of India's largest proposed AI infrastructure ecosystems. The first phase includes expanding GPU capacity at its Chennai campus to approximately 30 megawatts while developing a 40-megawatt AI-ready data centre in Mumbai. The infrastructure is intended to support hyperscalers, enterprises, research institutions and government organisations building AI applications across manufacturing, healthcare, financial services, energy and the public sector. The initiative aligns with Lakshya 2031, L&T's long-term growth strategy, which identifies digital infrastructure, cloud services and artificial intelligence as key growth engines. Alongside expanding AI-ready data centres, the company has strengthened its technology portfolio through investments such as its strategic stake in E2E Networks while leveraging businesses including LTIMindtree and L&T Technology Services to create an integrated digital ecosystem. As governments worldwide race to build sovereign AI capabilities, companies that control compute infrastructure rather than just software are expected to occupy a strategic position in the AI value chain. L&T's investment signals that India's AI ambitions extend beyond developing models to building the physical and digital infrastructure required to run them at scale. Building India's AI Backbone Subrahmanyan has consistently argued that AI requires more than algorithms it requires infrastructure. As enterprises move from experimentation to production-scale AI, access to secure compute, cloud platforms and data infrastructure is becoming as critical as traditional industrial assets. This philosophy reflects a broader global trend. Countries are increasingly investing in sovereign AI capabilities to reduce dependence on overseas infrastructure and strengthen digital resilience. L&T's strategy positions the company to participate in this transformation by combining its expertise in large-scale infrastructure delivery with emerging AI technologies. For an engineering company known for constructing roads, ports and industrial facilities, building digital infrastructure is a natural evolution rather than a departure from its core strengths. Leadership Beyond Technology Despite leading one of India's most significant AI infrastructure initiatives, SN Subrahmanyan has consistently maintained that technology alone cannot drive transformation. In L&T's FY2025 Annual Report, he emphasised that while AI is accelerating innovation, long-term value will continue to depend on human judgment, responsible deployment and disciplined execution. That balanced perspective reflects the leadership approach that has defined his career. Rather than pursuing technology for its own sake, he has focused on integrating new capabilities into L&T's long-standing engineering excellence and execution discipline. From Concrete to Compute As industries become increasingly digital, infrastructure itself is being redefined. The assets powering future economies will include not only highways, airports and power plants, but also AI factories, cloud platforms, GPU clusters and data centres. Under SN Subrahmanyan's leadership, L&T is positioning itself at the intersection of these two worlds. The company's strategy is not about replacing concrete with compute; it is about recognising that tomorrow's infrastructure will combine both. If that vision succeeds, L&T Chairman SN Subrahmanyan may be remembered not only for leading one of India's largest engineering companies but also for helping build the digital foundations of the country's AI economy.

Bharat’s Jetson Cities, Light-years Away from Nature

Updated: Jan 20, 2025

Jetson Cities

One thing is for certain: our Bharatiya cities, the big metros and towns, are fast becoming like the ‘Jetson’ cities. For those who are unaware of Jetson cities, these were first shown in the famous Hanna-Barbera cartoon series, the Jetsons, set in the 2100s, where cities are air-tight glass globules tethered to the ground, and the only way to get in and out are the flying cars. Yes, we, the city-dwellers, aspire to tall skyscrapers, spectacular bridges, world-class tunnels, swooshing metro trains, and we are building Jetson-like flying cars. A few HD drone images here and there, during the day and at night and around twilight, and we are content that our cities have become the cynosure of our own eyes. We want our cities to be brightly lit, with neon signs, laser shows, and large billboard videos. We would then fulfil our inner desire to have a city on par with Tokyo, New York, and Shanghai.


Our buildings, designed for the next 30 years, are well air-conditioned, shielding occupants from a soupy dust bowl of brown smog, soot, particulate matter, and fine dust. It is said that most new home buyers invest at least 10% of their property’s price in enhancing the interiors, soundproofing their homes, using air purifiers and conditioners, and disconnecting from the outside world for that much-needed solace. Indeed, large builders promote their projects as close to nature amidst tranquillity. However, there is always another builder eager to get one plot of land ahead of yours to enjoy that nature. To be truthful, access to nature now comes at a premium - even the skies.


Let’s assume the working-age population is occupied in the leisure of our Jetson cities, but how many of their young school and college-going kids have seen the long arm of the Milky Way galaxy from their cities? How many have witnessed a comet zooming by? How many know about endemic plants with medicinal properties? When did they last see a chirping house sparrow? How many know that the nearest sewage drain was once a freshwater stream? When did they last find their suburban beach prettier than the resort beaches of Maldives?


The intent to ask these questions is simple: Bharat is currently at a crossroads. Pundits are enthusiastic about a cultural renaissance on the horizon. Corporate leaders, on the other hand, want us to invest hundreds of hours each week to pay our dues to the growth of the national GDP. But no one asks, if a cultural renaissance is to occur, who will generate the new understandings and insights of nature that arise typically during such a period of human advancement? No one is actually asking, for whom are we building the nation if there is no time for children, or worse, if there is no time or intent to have children. In the process of growing rich, we are about to become old. By 2047, 65% of the population under the age of 35 will grow beyond 35 all at once, and we’d have an enormous population in advanced ages with a tapering young population, a graph that looks like a banyan tree. Unfortunately, that young population will have no access to the knowledge that nature has to offer, neither flora and fauna nor the seas and the skies.


Our urbane lifestyles need tempering. Such tempering can occur only if we ensure the revival of natural sciences during this period of cultural renaissance and nation-building. Let’s not rely solely on the educational system. With Indian Knowledge Systems, constructive changes are underway, and academic curricula are poised to improve for the greater good. However, true knowledge arises only when parents and grandparents introduce children to nature. Genuine understanding also develops from extracurricular activities in schools and colleges that encourage kids to observe, journal, and act on their discoveries. On the positive side, our country’s forest cover is increasing, as announced by the government. However, efforts must be made to ensure that every school or college, whether in Mumbai, Vijayawada, Gorakhpur, Ratlam, Thrissur, Bhuj, Faridabad, Imphal, Manali, Cuttack, or Ajmer, guarantees that their students are well aware of the endemic nature of their surroundings and are regularly observing and recording data on whatever interests them. Let kids observe rivers and understand the volume of water that flows through them. Let children learn about the decline of house sparrows in their cities and what steps should be taken to revive their populations. Let them study the bees in their nearby groves and recognise the vital role these bees play in nature.


Of course, you need to learn AI, robotics, fintech, the next generation of management courses, and all the engineering bells and whistles. However, we must not leave the next generation with inadequate comprehension and skills for understanding nature. We must ensure that nature conservation is not merely lip service or a tool for politicised green activists. This can be achieved if natural sciences are given the respect they deserve at the school, undergraduate, and postgraduate levels.


Indeed, I am a plebeian, and you might feel that you, too, could write a rant about the plight of our urban lives. Urban development and municipal experts have many solutions to propose, but few are willing to take action. However, that is not the issue I wish to highlight. I aim to illustrate a much larger concern—that Indian city dwellers are disoriented and devoid of nature, lacking a guiding star to lead them toward a brighter future. Our cities of Mumbai, Delhi, Bengaluru, Ahmedabad, Kolkata, and Chennai have taken on characteristics reminiscent of Jetson-like cities. We show little regard for the Nagar Devata, Gram Devata, and Van Devata, who have protected the cities, towns, and forests that once surrounded us. We wait for formal governance to clean up our beaches, rivers, and ponds without making sufficient efforts to prevent pollution in the first place.


For those striving to grasp spirituality not through the Puranas and Aadi-Granth but through new-age podcasts, I recommend watching Vinay Varanasi’s podcast on Bhagavan Vishnu’s Dashavatar. If it is clear that Bhagavan Vishnu does not tolerate disregard for Bhudevi or Mother Earth, why do we, the devotees of Bhagavan Vishnu, continue to pollute our Mother Earth—her air, soil, waters, and sounds? Or have we taken Elon Musk's words at face value, assuming our next destination is Mars after destroying Earth, only to ruin Mars later, even worse than its current clinically sterile state? If that is the case, then bear with me when I say this: these Jetson cities stand on precarious pillars of ego, victimhood, apathy, and consumerism, waiting to be toppled either by the true harbingers of order or by false prophets. Therefore, teach the next generations to observe nature, appreciate our coexistence with other species, and venerate the forces of nature. By doing so, we humans will be good, at least for the next thousand years. If not, prepare for a bleak future by the end of this century.
