Export controls may have helped turbocharge Chinese innovation.
The
 episode is in some ways a much bigger deal than Sputnik. Sputnik was 
about the Soviet Union’s space program competing with that of the United
 States. Few thought the Soviet economy in general was more 
technologically advanced than America’s. But DeepSeek is a private 
Chinese company that demonstrated its stunning prowess on the cheap in the most important technology for the future. It’s not exactly clear just how much
 DeepSeek’s model actually cost, to what extent it needed to use U.S. 
models for training and whether there was any closet Chinese government 
help. But given the enormous efforts that the U.S. government has made 
over the past few years to preserve its advantage — chip bans, export 
controls, etc. — DeepSeek has made a remarkable achievement. It suggests
 to me two lessons and two questions.
The
 first lesson is that, over time, open artificial-intelligence systems 
are likely to outperform closed systems. (An open system is like Lego 
blocks with instructions; a closed one is the built Lego structure with 
the instructions kept secret.) Many have pointed out that DeepSeek used Meta’s open-source Llama model to train. It also used Qwen, a family of AI models, also open-source,
 put out by the Chinese technology giant Alibaba. While DeepSeek is 
currently the best, China’s big technology companies have been releasing a number of AI models, mostly open-source,
 that are getting better and better. If the history of technology is any
 guide, the ability to see the innards of these models and understand 
their reasoning should lead to greater and faster technological 
innovation than using closed models that others cannot use for 
collaboration.
Second, constraints can be useful, as former Intel CEO Pat Gelsinger has noted.
 Just as art sometimes flourishes in repressive environments, in which 
restrictions force artists to be creative, so also engineers often 
operate best under constraints. Forced to use second-tier chips, Chinese
 engineers produced creative workarounds. This is not just true with 
DeepSeek. In 2023, Chinese telecommunications giant Huawei released
 a smartphone with a seven-nanometer chip, a kind that had been 
explicitly banned by U.S. export controls. There is some evidence that, 
after years of sclerosis, China’s chipmakers have responded to U.S. bans
 by becoming much more innovative.
In a fascinating interview last year, Liang Wenfeng, the CEO of DeepSeek,
 argued that his engineers were more motivated by doing research than 
making money, and appeared to contrast that attitude with the one 
prevalent in Silicon Valley, which is all about maximizing revenue, 
providing cloud services and generating cash flow. Demis Hassabis, who 
leads Google’s DeepMind and also shared the 2024 Nobel Prize in 
chemistry for AI-related scientific breakthroughs, is said to have 
fought to keep his team in London, far from Silicon Valley, so that it 
can focus on basic research.
The
 first question that DeepSeek raises is: Can the United States stop 
China from advancing along the technological frontier? Some argue that 
DeepSeek shows that export controls work: Its model needed many Nvidia chips,
 which it managed to procure before export bans were fully in place. 
Soon, China will not have access to the best chips and will suffer even 
more from the ban.
But as we have learned with the rounds and rounds
 of global sanctions against Russia, the world economy is large and 
porous. Stuff gets through. And China is not Russia. It is a vast, 
technologically sophisticated economy with millions of software developers
 and hundreds of high-quality firms in the technology space. Human 
talent on that scale will find ways to innovate, even if those measures 
keep China slightly behind.
The
 second question: What is the cost of this approach? If technology bans 
and export controls at best keep China behind a year — maybe just 
several months — is that gain worth the cost? That cost is Chinese 
retaliation, limiting the United States’ access to key materials that it
 needs for high technology. More important, a decoupled global economy 
also creates a closed ecosystem in which U.S. technology companies will 
not face competition from the best. Is Tesla going to innovate at the 
highest level if it is not facing its strongest Chinese rival?
A
 technology decoupling means that AI will become the central part of a 
new global arms race, totally unregulated and unconstrained, with the 
world’s two largest economies hurtling toward superintelligence 
no-holds-barred, and incorporating it into all military applications — 
including nuclear weapons. If artificial intelligence is as 
revolutionary a technology as predicted, having it unleashed in every 
realm of human life with absolutely no guardrails points to a scary 
future — one far more dangerous than anything people imagined because of
 the Sputnik satellite.
