关于软件工程与生成式AI的八大迷思

Generative AI is reshaping software engineering—but the narrative has gotten ahead of the evidence. Marketing claims, anecdotal wins, and misread studies have given rise to a set of persistent myths that are quietly driving poor decisions about AI adoption, tooling, and how to measure success. This article examines eight of the most common misconceptions. We already know developers don’t actually spend most of their time writing code, with studies at Microsoft and elsewhere showing it’s closer to 14 percent. That means AI code generation, even when it works well, touches a surprisingly small slice of the actual job. And yet organizations are doubling down on lines-of-code metrics to track AI’s impact, which is a measure that is neither statistically valid nor meaningfully connected to outcomes such as software quality or delivery speed. The reality is messier and more interesting than the headlines suggest. AI works better for some tasks, some developers, and some contexts than others. Productivity gains don’t flow automatically from handing engineers a license—they require rethinking workflows at the organizational level. Adoption stalls when developers don’t trust the tools, lack time to learn them, or worry about de-skilling. And the “startups move fast with AI” narrative ignores the compliance, legacy systems, and reliability constraints that define enterprise software. This article isn’t skeptical, but rather provides practitioners, team leads, and engineering leaders a clearer, research-backed picture so the decisions organizations make about AI are grounded in evidence, not just enthusiasm.
