Chapter 6, The Gremlin of Uncertainty, examines the pervasive role of uncertainty in both human and machine intelligence. Drawing on Pierre-Simon Laplace’s philosophical ideas, the chapter discusses “Laplace’s demon,” a thought experiment that imagines a being with perfect knowledge of all forces and positions in the universe. While theoretically compelling, Laplace’s demon underscores the limitations of real-world knowledge and computation, a problem the author refers to as “Laplace’s gremlin.”
The chapter explores historical examples to illustrate how humans have addressed uncertainty. During World War II, for instance, the U.S. Army Air Force established the Langley Field proving ground to test and improve the reliability of aircraft like the P-51 Mustang. Despite advancements, pilots attributed failures to “gremlins,” symbolic adversaries representing the unpredictable nature of machinery and war. These stories reflect humanity’s ongoing struggle with unpredictability and our tendency to anthropomorphize abstract concepts.
The text also discusses the evolution of probabilistic thinking, highlighting figures like Reverend Thomas Bayes, whose work laid the foundation for modern probability theory. These mathematical tools, coupled with the diversity of approaches seen in machine learning, offer strategies for navigating uncertainty. For example, algorithms balance computational shortcuts with data availability, mirroring the complementary improvisational and planned approaches humans use.
Ultimately, the chapter celebrates the value of diversity—in personalities, strategies, and methodologies—as key to resilience and problem-solving in an uncertain world.
