Review: AlphaGo
Introduction
AlphaGo (2017) is a fascinating documentary directed by Greg Kohs that explores the intersection of artificial intelligence and human intuition through the lens of the ancient board game Go. The film follows the groundbreaking development of DeepMind’s AI program, AlphaGo, and its journey to challenge and ultimately defeat some of the world's greatest human Go players, including legendary South Korean champion Lee Sedol.
The documentary is more than just a recounting of an AI triumph—it delves into the philosophical implications of artificial intelligence, human creativity, and the evolving relationship between man and machine. By weaving together expert insights, emotional reactions, and thrilling game footage, AlphaGo presents an engaging narrative about one of the most significant moments in AI history.
Plot Summary
The film begins by introducing the game of Go, a complex strategy board game with more possible moves than atoms in the universe. Unlike chess, where AI had already surpassed human grandmasters, Go was considered a final frontier for artificial intelligence due to its deep strategic and intuitive elements.
DeepMind, a British AI research company owned by Google, took on this challenge by developing AlphaGo, an advanced AI system designed to master the game through deep learning and self-play. The documentary follows the team of researchers, led by Demis Hassabis, as they train and refine the AI in preparation for its first major test: a match against European Go champion Fan Hui in 2015.
After AlphaGo's unexpected victory against Fan Hui, the AI’s next challenge was the legendary Lee Sedol, a 9-dan professional Go player known for his creative and unpredictable style. The film builds tension as the five-game match between Lee and AlphaGo unfolds, capturing the emotions of the players, the DeepMind team, and the global audience watching the historic event.
Direction and Cinematography
Greg Kohs’ direction strikes a delicate balance between technical depth and emotional storytelling, making an otherwise niche subject accessible to a broad audience. The documentary does an excellent job of humanizing the AI development process, showing the dedication, excitement, and uncertainty experienced by the DeepMind researchers.
The cinematography enhances the film’s intensity, especially during the pivotal matches. The use of close-up shots on Lee Sedol’s expressions, combined with dramatic lighting and suspenseful pacing, effectively conveys the gravity of each move. Meanwhile, interviews with AI experts, Go professionals, and commentators provide deeper context and insight into the implications of this technological breakthrough.
The film also features stunning visuals of Go boards, futuristic data visualizations, and behind-the-scenes footage from DeepMind’s headquarters, giving audiences a sense of both the traditional elegance of Go and the cutting-edge nature of artificial intelligence.
Themes and Symbolism
The Evolution of Artificial Intelligence
At its core, AlphaGo is about the rapid advancements in AI and machine learning. The documentary highlights how AI has evolved from rule-based programs to sophisticated neural networks capable of self-improvement. The development of AlphaGo represents a major leap in AI capabilities, showcasing how machines can develop intuition, creativity, and even surprise their own creators.
The Limitations and Strengths of Human Intelligence
One of the film’s most powerful themes is the contrast between human ingenuity and machine efficiency. Lee Sedol, once considered unbeatable, is faced with an AI that not only calculates possibilities but also generates moves that defy human logic. The now-famous Move 37 in Game 2, where AlphaGo made an unconventional yet brilliant move, symbolizes the moment AI demonstrated strategic creativity beyond human expectations.
At the same time, the documentary shows that humans possess something AI lacks—emotion, adaptability, and the ability to learn from failure in a deeply personal way. Lee Sedol’s stunning comeback in Game 4, where he delivered AlphaGo’s first and only defeat in the match, was hailed as a testament to human resilience and intuition.
Man vs. Machine or Man + Machine?
The film raises philosophical questions about whether AI should be viewed as a threat or a tool for human progress. While AlphaGo’s victory initially felt like a defeat for human intellect, the documentary suggests a different perspective: AI’s mastery of Go does not diminish human value but rather expands our understanding of the game and ourselves.
Go players around the world began analyzing AlphaGo’s moves, incorporating its strategies into their own play styles. This symbolizes a broader shift—humans and AI working together to push the boundaries of knowledge rather than being in direct opposition.
Strengths
✅ Compelling and Emotional Storytelling – The film skillfully combines human drama with technological advancements, making the story accessible and engaging even for viewers unfamiliar with Go or AI.
✅ Well-Paced and Suspenseful – Despite being a documentary, AlphaGo has the tension and excitement of a sports film, especially during the climactic Lee Sedol match.
✅ Philosophical Depth – Beyond AI and Go, the documentary explores profound questions about intelligence, creativity, and the evolving role of technology in human life.
✅ Beautiful Cinematography – The film features stunning visuals, from intense match scenes to elegant Go board aesthetics, enhancing the storytelling experience.
✅ Insightful Expert Commentary – The documentary includes valuable insights from AI researchers, Go professionals, and commentators, making complex concepts easier to understand.
Weaknesses
❌ Limited Discussion on AI’s Broader Implications – While the film focuses on AlphaGo’s impact on Go, it does not extensively explore AI’s potential consequences in other fields, such as healthcare, finance, or ethics.
❌ Somewhat One-Sided Narrative – The documentary mainly presents AI as a remarkable achievement, with limited exploration of concerns regarding automation, job displacement, and the risks of AI surpassing human intelligence in critical areas.
❌ Could Have Included More Go Historical Context – While the film explains the basics of Go, it does not delve deeply into the game's rich history, which could have added further depth to the narrative.
Historical and Cultural Impact
Since its release, AlphaGo has had a lasting impact on both the AI and Go communities. The film contributed to public discussions on AI’s role in society, sparking debates about the implications of machine intelligence.
In the world of Go, AlphaGo’s influence was profound. The AI’s moves revolutionized professional Go strategies, with top players studying and incorporating AlphaGo-inspired tactics into their gameplay. The defeat of Lee Sedol marked a turning point in the history of Go, demonstrating that AI could reach superhuman levels in fields once thought to be uniquely human.
Furthermore, AlphaGo paved the way for subsequent AI advancements. DeepMind continued to refine its technology, leading to AlphaZero, an even more advanced AI capable of mastering games like chess, shogi, and Go without any prior human knowledge.
The documentary remains an essential case study in AI development, frequently referenced in discussions on deep learning, human-AI collaboration, and the future of artificial intelligence.
Conclusion
AlphaGo is a captivating, thought-provoking, and visually stunning documentary that explores the boundaries of artificial intelligence and human ingenuity. By chronicling AlphaGo’s journey from an experimental AI to a world-class Go player, the film offers a compelling look at the potential—and limitations—of machine intelligence.
Greg Kohs successfully creates an emotional and intellectually stimulating narrative, making a technical subject accessible to a wide audience. Whether you are fascinated by AI, strategy games, or the philosophical implications of technology, AlphaGo is a must-watch documentary that will leave you questioning the future of human and machine intelligence.
