Introduction
In "AI Superpowers," Kai-Fu Lee, a renowned AI expert with experience in both Silicon Valley and China, explores the rapidly evolving landscape of artificial intelligence and its potential to reshape the global economy and power dynamics. Lee argues that China is poised to become a major player in the AI revolution, potentially surpassing the United States in many areas of AI development and application.
The book provides a comprehensive overview of the current state of AI technology, the differences between the AI ecosystems in China and the United States, and the potential impacts of AI on jobs, society, and the future of humanity. Lee draws on his unique perspective as someone who has worked in both Silicon Valley and China's tech sector to offer insights into the strengths and weaknesses of each country's approach to AI development.
The AI Revolution
Lee begins by explaining the recent breakthroughs in AI technology that have led to its rapid advancement and increasing real-world applications. He focuses on the development of deep learning, a subset of machine learning that has dramatically improved AI's ability to recognize patterns and solve complex problems.
The Breakthrough in Deep Learning
For decades, AI researchers were divided into two camps: those who favored rule-based systems and those who advocated for neural networks. Rule-based AI involved programming machines with specific rules, while neural networks aimed to mimic human learning through experience and data analysis.
The neural network approach, which eventually evolved into deep learning, required vast amounts of data and significant computing power to be effective. In the mid-2000s, these prerequisites finally became available, leading to a major breakthrough in AI capabilities.
In 2012, Geoffrey Hinton's team demonstrated the power of deep learning at a visual recognition contest, where their AI algorithm significantly outperformed traditional approaches. This event marked the beginning of the current AI revolution, as deep learning techniques could now be applied to a wide range of problems, including visual and audio recognition, complex financial decisions, and even autonomous driving.
The Four Waves of AI
Lee identifies four waves of AI development that are transforming various sectors of the economy:
Internet AI: This wave is already here, with algorithms powering recommendation systems on platforms like YouTube and news aggregators like Toutiao.
Business AI: This wave involves AI applications in traditional business sectors, such as financial services and healthcare.
Perception AI: This wave combines the digital and physical worlds through technologies like facial recognition and voice interfaces.
Autonomous AI: This wave includes self-driving cars, autonomous drones, and other AI-powered machines that can operate independently in the physical world.
China's AI Awakening
Lee argues that China has rapidly transformed from a copycat nation to a serious contender in the AI race. He points to several factors that have contributed to China's rise in the AI field:
The "Sputnik Moment"
In 2016, China experienced what Lee calls its "Sputnik moment" in AI when AlphaGo, an AI program developed by Google's DeepMind, defeated world champion Go player Lee Sedol. This event, watched by 280 million Chinese viewers, sparked a national determination to become a leader in AI technology.
From Copycat to Innovator
Lee explains that China's history of copying Western tech products actually helped prepare its entrepreneurs for success in the AI era. By replicating and adapting services like Facebook, Twitter, and Groupon for the Chinese market, Chinese entrepreneurs gained valuable experience in product development, user acquisition, and fierce competition.
One example is Wang Xing, who created Chinese versions of various social media platforms before founding Meituan, a group-buying service that outperformed Groupon in China. Wang's experience allowed him to create a product tailored to Chinese users' preferences and build a more sustainable business model.
China's Data Advantage
Lee emphasizes that China's unique online ecosystem gives it a significant advantage in AI development. Chinese tech companies often take a "heavy touch" approach, controlling multiple aspects of their services, which allows them to collect more comprehensive data.
WeChat, developed by Tencent, is a prime example of this approach. As a super-app, WeChat combines messaging, social media, mobile payments, and various other services into a single platform. This integration provides Tencent with a wealth of user data that can be used to train and improve AI algorithms.
The AI Race: China vs. the United States
Lee provides a detailed comparison of China's and the United States' strengths and weaknesses in each of the four waves of AI:
Internet AI
In this wave, Lee sees China and the United States as currently neck-and-neck, but predicts that China will have a 60-40 advantage within five years. China's larger internet user base and its population's willingness to embrace mobile payments and support content creators give it an edge in developing innovative AI-powered internet services.
Business AI
The United States has a significant advantage in this wave, which Lee estimates at 90-10 currently, potentially narrowing to 70-30 in five years. This advantage stems from the U.S.'s long history of detailed business record-keeping, providing a rich dataset for training AI algorithms in areas like finance and healthcare.
Perception AI
China leads in this wave, with Lee estimating a current 60-40 advantage that could grow to 80-20 in five years. Chinese consumers are more willing to trade privacy for convenience, allowing for faster adoption of technologies like facial recognition and voice interfaces. Additionally, China's manufacturing capabilities in Shenzhen enable the rapid development and deployment of AI-powered devices.
Autonomous AI
The United States currently leads in this wave, with Lee estimating a 90-10 advantage. However, he predicts this gap will narrow to 50-50 within five years. While U.S. companies like Google and Tesla are at the forefront of autonomous vehicle development, China's government is actively creating AI-friendly policies and infrastructure, including entire cities designed for autonomous vehicles.
The Impact of AI on Employment
Lee addresses the ongoing debate about AI's potential impact on employment, discussing various predictions and studies:
Job Displacement Estimates
Different studies have produced widely varying estimates of job displacement due to AI and automation:
- A 2013 Oxford University study suggested that 47% of U.S. jobs were at risk over the next 20 years.
- The Organization for Economic Cooperation and Development (OECD) estimated that only 9% of U.S. jobs were at risk.
- PriceWaterhouseCoopers (PWC) predicted that 38% of U.S. jobs were at risk.
- McKinsey Global estimated that around 50% of tasks worldwide are "already automatable."
Lee tends to agree with the PWC report but suggests that the actual number of displaced workers may be even higher due to "ground-up displacement." This refers to new AI-powered businesses that don't employ traditional workers from the start, rather than existing businesses automating jobs over time.
The Nature of AI-Driven Job Displacement
Lee emphasizes that AI is currently capable of automating specific tasks rather than entire jobs. For example, an AI tax advisor might be able to calculate tax returns and check for inconsistencies but cannot have nuanced conversations with clients.
However, he warns that the cumulative effect of task automation across various industries could still lead to significant job losses and economic disruption.
Rethinking Work and Society in the AI Era
After experiencing a personal health crisis, Lee developed a new perspective on the relationship between humans and AI. He proposes that the rise of AI presents an opportunity to reassess our values and create a more human-centered society:
Redefining Valuable Work
Lee suggests that we need to shift our perception of valuable work. Currently, highly-paid jobs are often those that generate profit, many of which can be automated by AI. Meanwhile, jobs that involve human-to-human interaction and caregiving are often undervalued and underpaid.
He argues that we should place greater value on jobs that cannot be easily automated, such as caregivers, teachers, and community workers. By doing so, we can address both the job displacement issue and improve the overall quality of life in our communities.
Universal Basic Income and Beyond
While Lee acknowledges that some form of universal basic income may be necessary to support displaced workers, he cautions against relying solely on this solution. Instead, he advocates for a more comprehensive approach that involves:
- Increasing wages for human-centered jobs like caregiving and community work.
- Allowing AI to generate profits in the corporate sector while redirecting those gains to support social services and human-centered work.
- Exploring alternative measures of societal progress, such as Bhutan's "Gross National Happiness" index, rather than focusing solely on economic metrics.
The Future of AI and Humanity
Lee concludes by discussing the potential long-term impacts of AI on society and human existence:
AI Utopia vs. Dystopia
Lee presents the ongoing debate between AI optimists and pessimists:
- Optimists like Ray Kurzweil and Demis Hassabis see AI as a tool to enhance human capabilities, cure diseases, and solve global problems.
- Pessimists like Elon Musk and Stephen Hawking warn of potential existential threats posed by superintelligent AI.
A Harmonious Future
Lee advocates for a middle ground, where humans and AI work in harmony. He envisions a future where:
AI takes over routine and mechanical tasks, freeing humans to focus on interpersonal relationships and creative pursuits.
Society places greater value on human-to-human interactions and community-building activities.
The economic gains from AI are distributed more equitably to support social services and human-centered work.
Humans leverage AI as a tool to enhance their own capabilities and solve complex global challenges.
