Bad code is kudzu
summary
Software features often act like invasive species, growing aggressively and becoming deeply embedded in a codebase even when they provide no value. This complexity builds up because adding features is rewarded, while removing them is a thankless task that rarely leads to professional recognition. To prevent codebases from becoming unmanageable, developers must actively prune unnecessary code. This is especially critical in the age of AI-generated code, which can accelerate the accumulation of useless complexity.
key points
- Features become sticky because other developers build new functionality on top of existing code, creating a dependency web that makes removal difficult.
- The current engineering culture prioritizes the shipment of new features over the deletion of old ones, leading to a systemic accumulation of technical debt.
- Using production analytics to identify unused features allows developers to make data-driven decisions about what to prune to maintain a lean codebase.

discussion positive
consensus
Commenters agree that the Kudzu plant analogy for bad code is an effective way to conceptualize technical debt and software decay. They argue that bad code, unlike visible invasive species, often hides in undisturbed areas of a codebase. The general sentiment is one that of intellectual curiosity, as they enjoy expanding the analogy to include 'hungry goats' as senior engineers who purge legacy code.
top insight
The most valuable perspective is that bad code behaves like an invasive species because it is easily copied by humans and LLMs, which allows it to dominate a codebase unless actively removed. This suggests that the exponential nature of code duplication requires removing 'weed' code much earlier than typically planned to prevent total system saturation.
