A New Tech Cold War Emerges in Lisbon
At the heart of Lisbon, Portugal, the Web Summit 2025 gathered over 70,000 tech leaders, innovators, and entrepreneurs from more than 150 countries. Known as the “Davos for geeks,” this annual event became a global stage where artificial intelligence, robotics, and startup ecosystems collided under the tense atmosphere of global tech rivalries.
As the world braces for the next wave of digital transformation, the event unfolded under a growing shadow—the deepening technological divide between the United States and China. Conversations stretched far beyond software innovation or startup funding; they touched the core of global power, trade restrictions, and who will dominate the algorithms shaping the future of civilization.
Global Rivalries Define the Summit’s Pulse
The presence of industry titans like Nvidia turned the summit into a microcosm of the world’s tech tensions. Rev Lebaredian, Nvidia’s vice president of omniverse and simulation technology, addressed the audience with an unfiltered truth: the Chinese market remains indispensable. Despite U.S. restrictions, Lebaredian emphasized that collaboration—not isolation—is the path to global advancement.
His words resonated across the summit halls: “Half the world’s computer scientists and computer engineers who are on the frontier of these technologies are in China.” For many, this statement crystallized the dilemma—the West may lead in innovation, but China holds the manpower and ambition to replicate and scale those breakthroughs.
Nvidia CEO Jensen Huang had already warned that China “is going to win” the AI race. Even though the country is cut off from Nvidia’s most advanced chips, its pace of development shows no sign of slowing. “If we try to exclude them,” Lebaredian warned, “they will find a way to develop the same things.”
The summit echoed with a subtle tension: is global innovation at risk of fragmenting into two competing spheres—one led by U.S. hardware, the other by Chinese ingenuity?
The Blackwell Ban and the Politics of Silicon
While developers discussed software revolutions and the next generation of robotics, the loudest message came from Washington. The U.S. government reaffirmed that Nvidia’s most advanced AI chip, the Blackwell, will not be sold to China.
White House spokeswoman Karoline Leavitt made the administration’s stance clear: “As for the most advanced chips, the Blackwell chip, that’s not something we’re interested in selling to China at this time.”
The message aligned with President Donald Trump’s earlier declaration—that these chips, the computational heart of modern AI, would remain exclusive to U.S. companies. Trump even suggested he might discuss the issue with Chinese President Xi Jinping during their summit in South Korea, but later admitted the topic “did not come up.”
Behind diplomatic language lies a deeper strategic calculation: control over AI chips is control over the digital future. Every data model, every autonomous machine, and every neural network ultimately runs on silicon. Restricting chip exports, therefore, isn’t merely a trade policy—it’s a modern form of power containment.
What Undercode Say:
The Web Summit 2025 reflects more than a gathering of minds—it’s a mirror of global anxiety. The world is witnessing a new kind of cold war, one fought not with missiles or armies, but with microchips, data, and machine intelligence.
The irony of the summit is hard to miss. While leaders talk about “connecting the world through technology,” their governments are actively building digital borders. AI, which was once seen as humanity’s collaborative frontier, is now being fenced by national interest.
Nvidia’s position is particularly symbolic. The company that powers much of the AI revolution finds itself torn between business expansion and geopolitical compliance. Its leadership acknowledges that excluding China is not a sustainable strategy, yet it must navigate U.S. sanctions that define its global operations.
Lebaredian’s statement—“We will lose the opportunity to work with them and benefit from the work that they do”—is not just an observation; it’s a warning. Innovation thrives in open ecosystems. When nations start hoarding knowledge or restricting access to key resources, the global rate of progress declines.
From a macroeconomic view, China’s human capital in computer science gives it an unmatched advantage. While the U.S. dominates chip design and high-end fabrication, China has been aggressively investing in domestic AI infrastructure, from language models to autonomous systems. The gap may narrow faster than expected.
The U.S. embargo on Blackwell chips may temporarily slow China’s hardware progress, but it could also accelerate domestic alternatives, leading to self-sufficiency and reduced Western leverage. This cycle has been observed before—in energy, rare earths, and telecommunications.
What the summit truly exposed is that technology and politics can no longer be separated. Every advancement in AI, every new chip architecture, and every global partnership carries an undercurrent of national strategy.
In that sense, the Web Summit has become a diplomatic battlefield disguised as a tech conference. Startups pitch investors, but governments watch closely, calculating alliances and dependencies. The “geek Davos” is slowly turning into a technopolitical theater, where innovation meets ideology.
If anything, this year’s Web Summit made one truth painfully clear: the future of AI will not be written by code alone—it will be shaped by power.
