2025 年 Stack Overflow 开发者调查（第 15 年）覆盖 177 个国家、314 种技术栈：84% 的开发者在用 AI 工具创新高，但正面评价从 70% 降到 60%，呈现“用得更多、满意更低”。最大痛点不是“完全错”，而是“差不多对但不完全对”（66%）；45% 认为调试 AI 生成代码更耗时。对准确性的态度分裂：46% 不信任、33% 信任，真正“高度信任”仅 3%；35% 访问 Stack Overflow 是为了解决 AI 相关问题。

AI Agent 仍未普及：52% 不用，其中 38% 明确没计划；每天用的只有 14%。但在使用者里，69% 认为提升生产力、70% 认为缩短特定任务时间——反映“效果存在但门槛更高”，核心是信任与风险：补全代码与让其自主操作文件/API 的代价不同。实践上，开发者把 AI 视为“需管理的助手”，而不是“自动驾驶”。

技术与角色趋势：JS/TS 使用率 66%，Python 同比 +7 个百分点到 58%；PostgreSQL 使用率 55.6%。模型使用上 GPT 系列用过的占 81%，Claude Sonnet 用过 42.8% 但好评率 67.5%（高于 GPT 的 61%），呈“叫好不叫座”。72% 反对 vibe coding（另有 5% 表示绝对不），约 15% 承认在做；AI 的“禁区”集中在部署/监控（76% 不打算用）、项目规划（69%）与提交/评审（61%）。调查首次单列“架构师”，6.1% 即进前四；同时 24.5% 表示工作快乐（去年 20%），32% 全远程，65% 从业超 10 年，63.6% 认为 AI 不威胁工作。

Stack Overflow’s 2025 developer survey (15th year; 177 countries; 314 stacks) shows AI is now mainstream: 84% use AI tools, yet positive sentiment fell from 70% to 60%. The biggest complaint is “almost right, but not quite” (66%), not being totally wrong. As a result, time shifts from writing to verifying: 45% say debugging AI-written code takes longer than their own.

Trust is the limiter. Accuracy is distrusted by 46% and trusted by 33%, and only 3% report high trust. AI Agents lag even more: 52% don’t use them (38% have no plan), and just 14% use them daily—though among users, 69% report productivity gains and 70% say certain tasks take less time. Developers prefer human-in-the-loop control, especially when tools can execute sequences or touch files/APIs.

Trends concentrate around pragmatic adoption. JS/TS remains #1 (66%), while Python rose 7 points to 58%; PostgreSQL leads databases at 55.6%. Model usage is uneven: 81% have used OpenAI GPT, while Claude Sonnet is used by 42.8% yet rates higher (67.5% vs GPT’s 61%). Most reject “vibe coding” (72% + 5% “absolutely not”; ~15% admit it) and draw hard boundaries around deployment/monitoring (76% won’t use AI), planning (69%), and code submission/review (61%). A new “architect” role appears at 6.1%, reinforcing that as coding gets cheaper, system design and accountability become the value center.
