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.

Lingua Pragmatica

Updated: Mar 20, 2025

As Southern leaders like M.K. Stalin rage against Hindi, Andhra Pradesh’s Chief Minister Chandrababu Naidu offers a model of pragmatism over parochialism.

Amid the cacophony of opposition in southern states to Hindi, Andhra Pradesh CM N. Chandrababu Naidu has taken a markedly pragmatic stance by remarking recently in the state Assembly that there was no harm in learning other languages. Hindi, Naidu noted, was useful for communication across India, particularly in political and commercial hubs like Delhi. His remarks, though avoiding explicit mention of the NEP, were widely seen as an endorsement of multilingualism and a rebuke to the linguistic chauvinism that has gripped parts of the South.


Few issues in India stir political passions quite like language. It is not merely a means of communication but a marker of identity, a relic of colonial resistance, and a source of political mobilization. In the southern states, where anti-Hindi sentiment has long been entrenched, the National Education Policy (NEP) 2020 and its three-language formula have reignited old tensions. No state embodies this defiance more than Tamil Nadu, where the ruling Dravida Munnetra Kazhagam (DMK) led by M.K. Stalin has framed the policy as an assault on its linguistic autonomy.


Naidu’s words, welcomed by his ally and Deputy Chief Minister Pawan Kalyan, mark a sharp contrast with the DMK’s position. Tamil Nadu’s hostility towards Hindi dates back to the 1930s, when C. Rajagopalachari’s attempt to introduce it in schools met with fierce resistance. The anti-Hindi agitations of the 1960s cemented the DMK’s ideological stance, with its first Chief Minister, C.N. Annadurai, famously warning that Hindi imposition could push Tamil Nadu towards secession.


The question, however, is whether this rigid opposition serves Tamil Nadu’s interests. While Stalin, with an eye to the upcoming Tamil Nadu Assembly polls, has been relentlessly portraying Hindi as a threat to his state’s regional identity, Naidu, a partner of the BJP-led Centre, is framing it as a tool for economic mobility. His argument is not that Hindi should replace Telugu or English but that it offers a competitive advantage.


The economic case for multilingualism is compelling. Indians who speak multiple languages tend to have better job prospects, higher earnings and greater geographic mobility. Andhra Pradesh’s Telugu-speaking diaspora is a case in point. Telugus make up a significant proportion of Indian-origin professionals in the United States, the Gulf, and Southeast Asia as Naidu pointed out, hinting that this success story was built not on linguistic rigidity but on adaptability.


In a country where inter-state migration is rising and where Hindi remains the most widely spoken language, refusing to learn it amounts to self-imposed isolation. Tamil Nadu’s approach, by contrast, risks limiting its youth. The DMK government has refused to implement the three-language policy, keeping schools strictly bilingual with Tamil and English. Its justification that Hindi is not necessary for global success could be true in a narrow sense but ignores the domestic context. If Tamil filmmakers can dub their movies into Hindi to expand their audience, why should Tamil students be denied access to the language that could open more doors for them within India?


The DMK has accused successive central governments, particularly under the Bharatiya Janata Party (BJP), of pushing Hindi at the expense of regional languages. Yet, rejecting Hindi outright is an overcorrection. The reality is that Hindi is an important language in India’s economic and political landscape. Naidu’s position, one of accommodation rather than confrontation, offers a middle ground that other Southern leaders would do well to consider.


Some states already recognize this. Karnataka, despite its own history of linguistic pride, has allowed Hindi to be taught as an optional language. Kerala, whose migrants work in Hindi-speaking regions and the Gulf, has been less hostile to Hindi education. Naidu’s model, balancing regional identity with practical necessity, offers a way forward. Languages should be embraced, not politicized. Southern leaders would do well to listen to him.
