The author argues that Knuth's vision of literate programming, where code is written for humans within a narrative explaining its logic, hasn't achieved mainstream adoption because it fundamentally misunderstands the nature of programming. Rather than a linear, top-down process suitable for narrative explanation, programming is inherently exploratory and iterative, involving frequent refactoring and restructuring. Literate programming tools force a rigid structure onto this fluid process, making it cumbersome and ultimately counterproductive. The author proposes "exploratory programming" as a more realistic approach, emphasizing tools that facilitate quick exploration, refactoring, and visualization of code relationships, allowing understanding to emerge organically from the code itself.
Hacker News users discuss the merits and flaws of Knuth's literate programming style. Some argue that his approach, while elegant, prioritizes code as literature over practicality, making it difficult to navigate and modify, particularly in larger projects.
