Summary of: Rebooting AI: Building Artificial Intelligence We Can Trust
By: Gary F. Marcus


In ‘Rebooting AI: Building Artificial Intelligence We Can Trust’, authors Gary Marcus and Ernest Davis argue that current AI technology is heavily reliant on deep learning and statistical models, lacking the cognitive processes that humans possess. They emphasize that, in order to revolutionize our lives, AI must be modeled after the human mind. This book summary will delve into the limitations of AI systems, highlighting their narrow scope and inability to adapt in open-ended worlds. You will also explore the challenges of creating human-like AI intelligence, as well as the importance of trust and ethics in AI systems that will shape our world and make decisions on our behalf.

Beyond Deep Learning

AI must go beyond statistical models and incorporate cognitive processes to navigate the world, empower robots and make ethical decisions, according to AI researchers Gary Marcus and Ernest Davis. The authors argue that for AI to truly change lives, it must resemble the human mind and possess a deeper understanding of the world.

The Limitations of AI

Marcus and Davis argue that while current AI lacks the capability to pose a significant threat or make a significant contribution to society, people tend to overestimate their abilities. AI systems are narrow and must be precisely programmed for each task, making them susceptible to errors when faced with new circumstances or unanticipated scenarios. Although AI may be proficient in closed systems like chess, it lacks the general intelligence, adaptability, and critical thinking skills that humans possess. AI is not a substitute for human knowledge and cannot replace human problem-solving abilities.

AI’s Struggle with Understanding the Real World

Deep learning is a revolutionary technology that processes immense amounts of data through hierarchical pattern recognition. However, it lacks understanding of the real world and causal relationships. It struggles with abstract concepts, partial information, and requires enormous amounts of data to perform human-like tasks. Even with large datasets, it can make errors, and its decision processes prove complex for experts to decipher. While it excels at finding surface statistical regularities in data, AI currently cannot read and understand real-world content, such as medical papers, as it lacks real-world experience from which to infer meaning. AI’s struggle with understanding language, translation, and compositionality highlights its limitations in high-stakes situations like interpreting a doctor’s notes. The real reason for AI’s limitations in understanding content lies in its inability to grasp basic knowledge about the world, as even understanding a simple children’s book passage would require vast amounts of real-world experience.

Overcoming the Myth of Superintelligent Robots

Contrary to popular belief, developing truly intelligent robots is incredibly difficult due to the complex nature of human intelligence. While robots excel in specific environments, they struggle to adapt to new situations and lack situational awareness. Additionally, there is no single “master algorithm” for intelligence as it requires a combination of prior knowledge and experiential learning. True artificial intelligence must constantly cycle through the “OODA loop” to observe, orient, decide, and act in real-time. Even with advanced hardware, creating software that can achieve basic intelligence remains a significant challenge. Ultimately, the human mind is far from a “blank slate” and relies on causal inferences based on both nature and nurture.
