The Tradeoffs of Using AI for Faster Development
The article discusses the author's experience using AI to boost development speed, but also encountering more difficult-to-catch bugs due to the AI's lack of contextual understanding about the codebase.
Why it matters
This article highlights an important tradeoff to consider when using AI for faster software development - the potential for more difficult bugs due to the AI's lack of contextual understanding.
Key Points
- 1AI assistance can significantly increase development velocity, up to 2x
- 2But the bug rate doesn't decrease at the same rate, as the AI-generated code can be plausible but break on edge cases
- 3The issue is 'confidence without context' - the AI doesn't know the specifics of the codebase and conventions
- 4Providing the AI with structured context files about the project can help reduce the class of 'confidently wrong' bugs
Details
The author shares their experience of using AI assistance for daily development, which has boosted their output velocity by up to 2x. However, they also noticed that the bug rate wasn't going down at the same rate. The issue is that the AI can generate well-structured, plausible code that still breaks due to lacking contextual understanding about the codebase, such as database schemas, library versions, or team conventions. This 'confidence without context' problem leads to harder-to-catch bugs. The author found that providing the AI with structured context files about the project's constraints, conventions, and known issues helped reduce this class of bugs, without sacrificing the overall speed gains from using the AI.
