Modularity - An Overrated Anti-Pattern? The Power of the Monolithic Script in the Age of AI.

Hello everyone 👋 I would like to share my experience (based on my project ), or rather advice on why refactoring is your (and even AI's) enemy and how to solve the problem if you are faced with breaking your monolithic 1000-line script into modules. The Problem We've all seen this path: a tiny script suddenly balloons to 500 lines. Then comes the moment when, following the advice of seasoned colleagues, we start the "proper refactoring": creating utils/ , parsers/ , and proliferating __init__.py files. But in an era where our main co-author is an LLM, this beauty becomes a hindrance. But why is modularity your enemy? If your code works in a single file, that's good. But your project grows. The line count increases. You start getting confused. You decide to refactor. You do it manually because you understand that an AI's advice will turn into another "find -> copy -> paste" quest.
