Ahead of the Trump-Xi summit, I joined @NPR’s @npratc on the U.S. - China tech race.
The common ground is thin, but real. While Xi rejects American technology restrictions, he also acknowledges shared concerns, including misuse of models to accelerate development of bio or chemical weapons or accidental escalation. That narrow space is where summit discussions can actually build future joint efforts.

Taiwan is a critical technology partner - one committed to building with U.S. beyond chips, from AI to recycling critical minerals, from electronics and chip production. Productive meetings with @bikhim, Defense Minister Koo, @josephwutw, and leaders across industry and R&D. I was also honored to deliver the closing keynote at the second annual Whole of Society Resilience Conference.

Our current approach to cyber defense isn't keeping pace with how adversaries use AI to attack critical systems. In my latest @ForeignAffairs article, "The New Chinese Way of Cyberwar: How Beijing Will Weaponize Digital Chokepoints", I outline a new approach. Read it below - eager for your thoughts.

Defense tech is changing the pace and scale of innovation for America's military and militaries around the world. Not every ally brings the same thing to the table — some are diplomatic partners, some have got real game. Being strategic about how we leverage tech and allies matters more than ever in a world that's geopolitically unstable.
I unpacked this with @NGirishankar for @CSISEST's Betting on America.
🔴 Live now on Betting on America: Technology Is Security
@AnneNeuberger, General Partner and Head of Global Affairs at @a16z and former Deputy National Security Advisor for Cyber and Emerging Technology, joins Betting on America with @NGirishankar to make the case that technology leadership is security. She argues that sustaining leadership has become increasingly challenging as acceleration technologies like AI, robotics, quantum, and cyber converge, creating significant upsides for innovation but also downside risks. These technology disruptions will require policymakers, investors, and our alliances to adapt rapidly.

Today, I’m excited to join Andreessen Horowitz as a General Partner and Head of Global Affairs.
This is my next chapter in the mission of securing America at home and ensuring technological innovations are adopted to keep us safe, working together with our allies to build a more secure and prosperous future.
Today, as the U.S. and China compete on the global stage, the spread of technology is tinged with geopolitics and more fragmented.
Security now requires a focus on digital sovereignty, supply chain resiliency, and the trustworthiness of the infrastructure underpinning our economies and our national security.

Cybersecurity is becoming a contest between AI systems used by attackers and their targets. The decisive factor is which side has richer data and better models and can act at machine speed, writes @AnneNeuberger

In an AI era when attackers can jiggle every virtual doorknob continuously, human defenders don’t stand a chance. What matters is how fast we deploy digital defenders to jiggle those doorknobs—and tighten them—beforehand.
We need a network of secure defensive agents that can reason and react faster than any human.

The robotics race is going to determine the future of our national security.
If we don’t act soon, it’s China’s race to lose.
Here’s how China is winning, and how we can catch up:

We’ve seen this playbook before – like in solar PVs. First Chinese firms enter the market. They rapidly learn how to manufacture more cheaply than competitors. They undercut rivals, then either buy them or drive them out of business. The end state: total Chinese supply chain dominance.
It’s already the case that American companies that want to build robots are reliant on Chinese parts. But in a few years, Chinese suppliers might be totally dominant in the global market.

If we don’t act, China’s lead is going to be too big to overcome. Given how important robotics is going to be, we need to get serious.

America is celebrating its AI software lead. But we're missing the bigger picture.
China has more robots in production than the rest of the world combined. Unitree is selling advanced humanoids for $5,900. China has entire "dark factories" factories that run with zero humans.
Jensen Huang says the “ChatGPT moment for general robotics” is coming. China is ready. Right now, the United States is not.

In 2023, China installed 276,000 robots.
America installed 38,000.
We can't let China win the robotics race.
