TechSurge: Deep Tech Podcast

For thirty years, the United States largely ignored critical minerals. We mined less, processed less, and stockpiled less — while China quietly built the most dominant mineral supply chain in modern history. When China imposed rare earth export restrictions in 2024, manufacturers from Detroit to Tokyo scrambled. The invisible inputs powering electric vehicles, semiconductors, AI data centers, and defense systems had suddenly become visible — and vulnerable.

In this episode of TechSurge, host Sriram Viswanathan speaks with Dr. Gracelin Baskaran, Director of the Critical Mineral Security Program at the Center for Strategic and International Studies. A mining economist with over a decade of field experience across Africa, Latin America, Asia, and the Middle East, Gracelin is one of the sharpest minds working on how the world secures the raw materials that make advanced technology possible.

Gracelin brings a clarifying perspective to a topic that is often framed as a geopolitical contest: the real challenge, she argues, is economic. Until mining in allied countries is genuinely profitable — until the capital, energy infrastructure, processing technology, and policy stability are all in place — supply chain security remains aspirational, regardless of how many executive orders get signed.

Sriram and Gracelin work through the full landscape: what critical minerals actually are and why the term matters, how China built its dominance not just through geology but through industrial strategy and foreign policy, and why the 29-year average timeline from mineral discovery to production creates a fundamental tension with the pace of technology investment. They examine the gap the CHIPS Act left unfilled, the case for aggregating allied demand to change the economics of new mines, and what tech CEOs are dangerously wrong to assume about their own supply chains.

They also dig into the emerging policy architecture: Project Vault as a demand-driven civilian stockpile, the critical minerals ministerial that brought 55 countries to Washington, and the role of recycling and AI-driven exploration in accelerating a supply chain that cannot be built on mining alone.

Ultimately, Gracelin argues that America's greatest advantage is not its geology — it is its capacity to innovate. But innovation without investment, and investment without durable policy, will not be enough. The window is open. The question is whether the commitment holds.

For years, crypto policy in the United States was defined less by clear rules than by the threat of enforcement. Startups and institutions building in the space operated in a gray zone: no clear guidance, no path to compliance, and always the possibility of a regulatory hammer coming down. In 2025, that began to change.

In this episode of TechSurge, host Sriram Viswanathan speaks with Commissioner Hester Peirce of the U.S. Securities and Exchange Commission — one of Washington's most closely watched voices on digital asset policy. Known informally as "Crypto Mom" for her consistent advocacy that markets work best with clear rules and room to innovate, Commissioner Peirce was designated in 2025 to lead the SEC's first Crypto Task Force, signaling a more structured, collaborative approach to digital asset regulation.

Commissioner Peirce brings a rare perspective: a regulator who believes that ambiguity does not protect investors — it protects incumbents and rewards bad actors. In this conversation, she explains what has actually changed in 2025, what it means for companies building in crypto, and what it will take to make this regulatory progress durable beyond any single administration.

Sriram and Commissioner Peirce work through the full landscape: why "crypto" is not one thing but several, how the SEC thinks about Bitcoin as a commodity, what tokenization of traditional securities actually requires, and where real policy gaps remain. They also examine the role of stablecoins and CBDCs, the tension between investor protection and permissionless innovation, and how vertical integration in crypto markets raises the same questions the financial system has always faced — just with new architecture underneath.

Ultimately, Commissioner Peirce argues that the best regulatory framework is one that lets markets identify where technology is useful, enforces rules fairly and consistently, and makes enough room for people to build real things that solve real problems. Once those products exist and are woven into daily economic life, she argues, they become durable — regardless of who is in office.

Digital imaging is so ubiquitous today that it’s easy to forget how improbable it once was. In this episode of TechSurge, guest host Nic Brathwaite sits down with Dr. Eric Fossum, inventor of the CMOS active pixel image sensor, to unpack the breakthrough that made it possible to embed cameras into billions of devices and the deeper lessons behind it.

Eric explains how his work began not with consumer electronics, but with a NASA constraint: how to shrink a refrigerator-sized space camera into something small enough for spacecraft. The solution required a fundamental shift in architecture. By moving from CCD-based imaging to CMOS, where sensing and processing could happen on a single chip, he enabled a level of miniaturization and scalability that transformed cameras from standalone systems into embedded infrastructure.

But the conversation goes far beyond the invention itself. Nic and Eric explore what it takes to commercialize deep technology, from the early days of Photobit to its acquisition by Micron, and the critical role ecosystems play in turning breakthroughs into global platforms. They discuss why intellectual property is less about protection and more about leverage, and why even the most important inventions require manufacturing scale, capital, and partnerships to succeed.

The episode also looks forward. As AI systems increasingly rely on visual and physical data, sensors are shifting from tools designed for human perception to components optimized for machine intelligence. Eric highlights the challenges of pushing intelligence to the edge, the limitations of current architectures, and the growing importance of sensing technologies beyond traditional imaging—including molecular detection and new materials that go beyond silicon.

While much of today’s investment is concentrated in models and compute, this conversation makes the case that the next wave of innovation may come from deeper layers of the stack, where machines interact directly with the physical world. The future of AI may depend not just on how systems think, but on how they see, detect, and understand their environment.

As artificial intelligence becomes a strategic capability for nations as well as companies, questions of governance, safety, and geopolitical competition are moving to the forefront. In this episode of TechSurge, host Sriram Viswanathan speaks with Helen Toner, Interim Executive Director of the Center for Security and Emerging Technology (CSET) at Georgetown and a former OpenAI board member, about the rise of sovereign AI stacks and the global implications of increasingly powerful AI systems.

Helen brings a rare vantage point from both inside the frontier AI ecosystem and the policy world. She reflects on lessons from her time on the OpenAI board, including the governance challenges that arise when nonprofit missions intersect with enormous commercial incentives and rapid technological progress. As AI capabilities accelerate, she argues that the industry is still grappling with deep uncertainty about how these systems work, how they will evolve, and what responsibilities companies and governments should carry.

The conversation explores the idea of sovereign AI; the growing push by countries to control key layers of the AI stack, including compute infrastructure, models, and data. Helen explains why governments increasingly view AI as a strategic national resource, comparable to past transformative technologies like electricity or the internet. At the same time, she cautions that full technological independence may be unrealistic for most nations, given the complexity and global interdependence of the AI supply chain.

Sriram and Helen also examine the evolving US–China AI competition, the role of export controls and semiconductor supply chains, and how different countries, from China to emerging AI hubs in the Middle East, are positioning themselves in the race to build advanced AI capabilities. Along the way, they discuss whether the industry should slow down development, how companies are experimenting with “safety frameworks” for frontier models, and why installing guardrails may be more realistic than attempting to halt progress altogether.

Ultimately, Helen argues that society is entering a period of profound uncertainty. AI is transitioning from a research discipline into a foundational system that will shape economies, security, and daily life. Navigating that transition will require not just technical breakthroughs, but new approaches to governance, transparency, and global cooperation.

As generative AI systems move from novelty to infrastructure, questions of safety, trust, and governance are becoming urgent. In this episode of TechSurge, host Sriram Viswanathan is joined by Dr. Rumman Chowdhury, CEO of Humane Intelligence PBC and responsible AI Pioneer, about what AI safety really means and why the industry may be focusing on the wrong problems.

Rumman argues that the most overlooked lever in AI development is evaluation. While companies emphasize model training and capabilities, far less attention is paid to how systems are assessed in real-world contexts, who defines “good,” what risks are measured, and how societal impacts are accounted for at scale. She distinguishes between technical assurance and broader sociotechnical risk, from misinformation and bias to over-reliance and erosion of institutional trust.

Drawing on her experience at Twitter (X) and in global policy circles, Rumman highlights a fundamental governance gap: unlike finance, aviation, or healthcare, AI lacks a mature, independent ecosystem of auditors and evaluators. Today, the same companies building AI systems often define what counts as harm. She also challenges the belief that stronger guardrails alone will solve the problem, noting that cultural context, language differences, and human behavior complicate any notion of “neutral” or fully objective AI.

Rather than focusing solely on speculative existential threats, Rumman urges attention to the harms already visible from AI-enabled misinformation to mental health risks and shifts in how younger generations relate to knowledge and authority. The future of AI, she suggests, will be determined not just by technological breakthroughs, but by whether we build credible systems of accountability, evaluation, and global cooperation around them.

As global supply chains fracture, AI reshapes productivity, and technology becomes a core instrument of national power, India is making an ambitious push to redefine its role in the world economy from IT services provider to deep tech superpower.

In the season 2 premiere of  TechSurge, host Sriram Viswanathan brings together three defining perspectives to examine how India is positioned to become a global leader in frontier technologies, and what must go right for that vision to succeed.

The episode begins with S. Krishnan, Secretary at India’s Ministry of Electronics and Information Technology, who outlines how India is treating deep tech as national infrastructure. From the India Semiconductor Mission and AI compute investments to the new RDI (Research, Development & Innovation) framework, Krishnan explains how long-horizon industrial policy is being used to derisk private capital, strengthen domestic design and manufacturing, and accelerate commercialization.

Next, former G20 Sherpa Amitabh Kant places India’s technology ambitions in a global context. As post-WWII institutions weaken and supply chains are redrawn, Amitabh argues that India’s decade of structural reforms, digital public infrastructure, and global partnerships has created a historic opening, if India can sustain free enterprise, execution discipline, and state-level reform.

Finally, T.K. Kurien, CEO and Managing Partner of Premji Inves, brings the investor and operator lens. Kurien explores why India has excelled at services and business-model innovation but lagged in core technology creation and what it will take to build globally dominant deep tech companies. From patient capital and university-led innovation to focused national bets in AI applications, biotech, and semiconductors, he outlines the path from ambition to execution.

Across policy, geopolitics, and capital, one message is clear: India’s deep tech future will not be decided by vision alone but by alignment between government direction, private risk-taking, and long-term discipline.
