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.

Caste-based Census Sparks Nationwide Debate

Updated: Oct 22, 2024

Caste-based Census

Caste-based identities continue to dominate rural India, directly or indirectly shaping electoral outcomes. Many major elections are influenced by specific caste groups. After the Bihar government released the first phase of its caste-based socio-economic survey, the caste census became a hot topic. The results, backed by evidence, showed improvements in the living standards and social status of marginalised communities, both in cities and villages. With parties like the JDU and NCP backing a caste census, there is growing momentum for the government to conduct one. However, every story has two sides—joy and sorrow. Even Mahatma Gandhi, the Father of the Nation, raised concerns about the caste census.

Rahul Gandhi accused the BJP of being “anti-Bahujan.” The clear meaning is that his father and forefather refused to execute a caste-based census, which might have far-reaching effects and even permanently fracture India’s social fabric. This may be negative for caste-based beneficiaries. The last caste census in India was conducted in 1931 by the British government. Those times were different from the present scenario. The data was made public and became the basis for the Mandal Commission Reports and reservation policies for Other Backward Classes. Rashtriya Swayamsevak Sangh (RSS) has clarified that the caste-based population count data will not be used for core politics. But the agenda for politics is always twisted and expanded.

The Central Government also joined the legal debate by filing an affidavit with the Supreme Court, leaving the matter unresolved. India’s partition, rooted in the divide-and-rule strategy, is frequently cited as a cautionary tale. Including caste in official census data could further deepen social divides. This issue has become a political pressure point, with various states pushing the Centre for action. Although the Constitution uses the term “class” instead of “caste,” the Supreme Court has consistently ruled that caste is a relevant, and at times, sole or dominant criterion for defining a backward class.

After the release of caste-based census data in Bihar, discussions around conducting similar censuses have gained momentum in states like Rajasthan, Chhattisgarh, and Jharkhand. Karnataka, which has already conducted its own caste census, may release its data soon as well.

Notably, all these states are governed by anti-BJP parties. Congress leader Rahul Gandhi also announced that Congress-ruled states have committed to carrying out caste censuses. Meanwhile, the BJP has remained silent on the matter, creating a significant roadblock.

Caste-based censuses focus on proportional representation in areas like jobs and education, with the argument that this will aid in targeted planning for the disadvantaged. However, the situation remains unclear, much like a foggy winter morning. The BJP’s stance on caste-based censuses and reservations seems different, as they fear the caste-based calculations could fragment their traditional Hindu voter base—an underlying concern for the party.

Professor Sanjay Kumar from The Centre for the Study of Developing Societies, says, “Let alone the BJP; no party can openly oppose it; it is not free from danger. BJP gets a large number of votes from the OBC community, their population across the country would be around 52%. Another downside is that the caste-based censuses could disrupt the balance of socio-economic zones. Data theft is a common issue in government systems, and people may feel disconnected from their actual rights.

The moot question is that if the financial status of an ST/SC/OBC or Dalit citizen moves up by a few notches, will his social status change automatically? The lifestyle of any class will only change when the income of a particular class is changed. The actual source of income is employment. The reality is that only metro cities have enough place and space for workers. Aside from the GIDC and IT sectors, less than 30% of industries have their own designated vacancy periods. After a decade, the Jamnagar and Rajkot Corporations have opened their doors to newcomers alongside experienced staff. However, age and caste bias often operate behind the scenes. It’s important to recognise that poverty is also widespread among many upper-caste individuals, and their needs cannot be overlooked. In the overall interests of the nation, terms like SC/ST/OBC, Dalits, etc. must be deleted from the nation’s vocabulary. Every citizen should have only one classification, that of being an ‘Indian’, in the spirit of the constitution.

Last year, when the Bihar government decided to conduct a caste survey in the state, the BJP was also Nitish Kumar’s partner in the state government, and it supported it. Political expert and former professor of Tata Institute of Social Science, Pushpendra Kumar, says, “It is not that the BJP does not talk about caste. It tries to reveal the caste of the Prime Minister as well. For caste politics, the BJP also tried hard to raise the issue of Pasmanda Muslims.”
