Overview
In “The Worlds I See,” I share my personal journey from immigrant to AI pioneer, tracing the path that led me to champion a human-centered approach to artificial intelligence. The book explores the intertwined threads of personal experiences, scientific curiosity, and a deep commitment to using technology for good. It’s intended for anyone interested in AI, technology, and the future of our world, especially those working in or considering a career in these fields.
I begin by describing my childhood in China, where my parents’ intellectual curiosity and struggles as immigrants instilled in me a drive to explore and a belief in the transformative power of ideas. This foundation led me to physics, where I found the beauty of scientific inquiry and a sense of belonging that transcended cultural divides. My experiences as a young immigrant in the US, juggling multiple jobs while pursuing my education, further fueled my determination.
As I delve into my career in AI research, I highlight the importance of curiosity, mentorship, and collaboration. The book chronicles my work on ImageNet, a large-scale visual database that revolutionized computer vision, and my efforts to make AI more inclusive and accessible through AI4ALL. I explore the ethical implications of AI, including bias, fairness, and privacy, and the urgent need to consider its impact on human lives and society.
The narrative weaves together personal anecdotes with key developments in AI, from the early days of neural networks to the rise of deep learning and the latest breakthroughs in generative AI. It emphasizes the essential role of data in shaping intelligent systems and underscores the importance of understanding how our own brains work as a key to unlocking the mysteries of intelligence. Throughout, I advocate for a human-centered approach to AI, emphasizing that technology must be designed to enhance human capabilities and serve human needs, not the other way around. The book closes with a call to action, urging readers to join the effort to shape the future of AI in a way that is ethical, inclusive, and beneficial for all of humanity. human-centered AI, data-driven science, visual intelligence

Key Takeaways
1. AI should be human-centered.
My personal experiences, from struggling to navigate a new culture as a teenager to caring for my ailing mother, taught me the importance of putting people first. I believe that AI should be designed to serve human needs, not the other way around. This involves focusing on usability, accessibility, and the impact of the technology on individuals and communities. It also means considering the ethical implications of AI and working to mitigate potential harms like bias, surveillance, and job displacement.
Practical Application:
When designing a new AI product, prioritize the user experience. Conduct thorough user research to understand their needs, values, and concerns. Design the interface and interactions to be intuitive, accessible, and respectful of user privacy. Solicit feedback throughout the development process and iterate based on user input.
2. Data is crucial in AI development.
My work on ImageNet demonstrated the critical role of large-scale, diverse data sets in training AI models, particularly deep learning algorithms. The size and variety of the dataset allowed our models to learn more effectively and generalize better to new, unseen images. This insight has become increasingly important in the era of deep learning, where the availability of large data sets has fueled many of the field’s breakthroughs.
Practical Application:
When training an AI model, experiment with different datasets of varying sizes and characteristics. Don’t just rely on standard benchmarks. Explore the use of diverse, real-world data, even if it’s messy or incomplete. Analyze the model’s performance across different datasets to understand its strengths and weaknesses and identify potential biases.
3. Collaboration is key to AI innovation.
My career was shaped by the guidance of mentors and collaborators from various fields, including computer science, electrical engineering, neuroscience, and medicine. My work on ambient intelligence for health care, for example, would not have been possible without collaboration between computer scientists, clinicians, and ethicists. These experiences taught me that true innovation often comes from bringing together diverse perspectives and expertise.
Practical Application:
Actively seek out mentors and collaborators from different disciplines. Attend conferences and workshops outside your area of expertise. Engage in interdisciplinary research projects. Build diverse teams with members from a variety of backgrounds.

Comparative Analysis
Compared to other books on AI, like “Life 3.0” by Max Tegmark or “Superintelligence” by Nick Bostrom, which explore the potential existential threats of advanced AI, “The Worlds I See” offers a more personal and grounded perspective. While acknowledging the potential risks, I focus on the human element of AI, drawing on my personal experiences to highlight the importance of human-centered development. My book also provides a unique historical overview of the field, showing how progress is often driven by a combination of scientific curiosity, collaboration, and serendipitous discoveries, rather than solely by theoretical breakthroughs. Unlike books that focus solely on the technical aspects of AI, “The Worlds I See” emphasizes the societal and ethical implications of the technology, urging readers to consider its impact on human lives and communities and to actively participate in shaping its future. I also explore the significant role of large-scale data sets, a concept often overlooked in popular AI literature.
Reflection
As I reflect on the themes of “The Worlds I See,” I acknowledge the rapid evolution of AI since the book’s publication. While the core message of human-centered AI remains relevant, the advent of large language models and generative AI raises new questions and challenges. My emphasis on data-driven approaches, while instrumental in the deep learning era, might require reevaluation in the context of models trained on massive text and code datasets. The ethical considerations I raised, particularly regarding bias and surveillance, have become even more pressing with the increased capabilities and widespread deployment of AI. My personal experiences continue to shape my perspective, reminding me that the human element of technology should always be prioritized, even as the lines between human and machine intelligence become increasingly blurred. The book’s strength lies in its personal and accessible approach to complex topics, but its focus on computer vision might feel somewhat narrow in today’s rapidly expanding AI landscape. Overall, “The Worlds I See” serves as a starting point for a deeper conversation about AI’s role in our lives and the future of humanity.
