Using AI can create an illusion of flow in coding, making it easier to write more code and deliver features faster, but this can also mask a "depth problem" where the AI's output may not be a direct translation of the user's intent, making it difficult to evaluate the quality of the code. In contrast, traditional text editors like Vim provide a direct and transparent relationship between the user's intent and the output, allowing for better evaluation of the code's quality. This disparity can lead to an "empathy gap" where non-engineers may underestimate the complexity and effort required to develop high-quality software. AI summary
