Battle for the AI Data Center: Deep Dive on the Semiconductor Supercycle with Stacy Rasgon

For most of human history, space has been a place we visited. The next chapter may be about building there.

For decades, space was the domain of governments, astronauts, and science fiction. Today, falling launch costs, reusable rockets, and a new generation of ambitious founders are turning orbit into something else entirely: a place to build. The question is no longer whether humanity can construct large-scale infrastructure in space, but what we should build first-and why.

In this episode of TechSurge, host Sriram Vishwanath speaks with Dr. Ariel Ekblaw, Founder and CEO of Aurelia Institute, Research Affiliate at MIT’s Space Exploration Initiative, and founder of Rendezvous Robotics. Ariel has spent her career exploring one of the most fundamental challenges of the emerging space economy: how to build structures in orbit that are far larger than anything that can fit inside a rocket.

Ariel explains the origins of TESSERAE, her pioneering work on autonomous self-assembling space architecture, and how ideas borrowed from biology, swarm intelligence, and modular construction could unlock a future of massive solar arrays, communications infrastructure, orbital laboratories, and eventually human habitats in space.

The conversation explores the rapidly emerging market for in-orbit infrastructure, including AI data centers in space, space-based solar power, and the technologies needed to support a permanent industrial presence beyond Earth. Ariel breaks down the engineering realities behind these ideas—why cooling data centers in space is harder than most people assume, how autonomous assembly could solve the scale problem, and why the future of orbital infrastructure may look more like a business park than a collection of standalone satellites.

Sriram and Ariel also discuss the broader implications of humanity’s return to space: the economics unlocked by reusable launch systems, the opportunities created by dramatically lower transportation costs, and the second-order innovations that may emerge from building an industrial ecosystem in orbit. Along the way, they examine space debris, stewardship of the orbital commons, artificial gravity, and what it will take to make long-term human habitation in space viable.

At the heart of the discussion is Ariel’s belief that space is not an escape from Earth’s problems, but a tool for solving them. Whether through advanced manufacturing, new energy systems, biotechnology research, or entirely new industries, she argues that the next era of space exploration should be focused on improving life here at home.

For years, the United States told itself a reassuring story: China could manufacture and copy, but it couldn't innovate. That story is no longer credible. From DeepSeek's compute-efficient AI model to BYD's dominance of the global EV market, China is producing both volume and quality across sectors that matter. The question is no longer whether China can compete — it's whether the United States is playing its own hand well.

In this episode of TechSurge, host Michael Marks speaks with Vivek Chilukury, Senior Fellow at CNAS, where he focuses on U.S.–China technology competition, AI policy, and digital geopolitics. Vivek's path from counter-terrorism work at the State Department to tech policy in the Senate gives him an unusually grounded perspective on how government actually functions — and where it keeps failing itself.

Vivek and Michael work through the full competitive landscape: the wake-up moments that shifted Washington's focus from manufacturing to technology dominance, why the dual-use nature of advanced technology has pulled the national security community into conversations once left to industry, and what Made in China 2025 actually achieved — and where it fell short.

The conversation goes deep on America's policy toolkit: what the CHIPS Act accomplished and why it wasn't enough, how export controls on advanced semiconductors are working and what they're missing, and why Washington is far too weighted toward restriction at the expense of the "run faster" side of the equation. Vivek is also candid about what DeepSeek really tells us — not just about Chinese innovation, but about the gap between building a model and deploying AI at scale.

They also explore the global dimension: China's "easy button" approach to technology exports, what the U.S. AI exports program is trying to do in response, the rise of "AI sovereignty" movements from Brussels to Delhi, and why the talent and immigration decisions of the past year amount to a serious self-inflicted wound.

The United States still holds the best hand in the world for this competition. The question Vivek keeps returning to is whether we're playing it well — and right now, his honest answer is no.

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.
