不像 GitHub CEO Thomas Dohmke 那样，一边喊着"要么拥抱 AI，要么离开"，一边忙着卖 Copilot 订阅，真正带队写代码、扛事 故的 CTO 们，对"氛围编程"的态度冷静得多，也残酷得多。 他们没有利益冲动去推销新概念，更没有时间沉迷话术，他们面对的只有实打实的线上系统、真金白银的技术债和凌晨的报警电 话。也正因为如此，他们的结论比任何口号都更值得参考。 在 CTO 的叙述里，氛围编程并不是"生产力革命"，而是一场接二连三的灾难。 一位 CTO 说得很直白："氛围编程看似捷径，但本质是死路。" Let Set Go 的 CTO Ritesh Joshi 的团队刚经历过一次"教科书式"事故：开发者用 AI 生成了一段数据库查询，小样本下毫无问题， 但一旦遇到真实流量，系统立刻被拖到爬不动。问题不是语法有错误，而是底层架构。 Cirrus Bridge 的创始人兼首席软件架构师 Patric Edwards 也分享过一次"惊心动魄"的经历：一名新人把 AI 建议和 Stack Overflow 代码片段拼凑起来，写了个用户权限系统。测试和 QA 全部通过，上线后两周才发现已注销的用户依 ...

Core Viewpoint - The article discusses the harsh realities faced by Windsurf employees after the company was acquired by Cognition, highlighting the pressure to conform to a demanding work culture characterized by a "996" work schedule, which entails working six days a week for over 80 hours [1][3][5].
