Microsoft distinguished engineer David Fowler says 'typing code is absolutely over' and Windows 11 is already built that way
Fowler, an 18-year Microsoft veteran who leads Aspire, posted the remark on X on 2026-09-05, arguing developers now own architecture, testing, performance and security review while agents produce the code. The supporting numbers in the coverage are Nadella's earlier 20-30% of Microsoft code written by AI, a July 2026 Windows 11 update patching 570 bugs attributed partly to AI-assisted vulnerability detection, and Copilot's coding agent building WinUI apps in 30 minutes. The 351-upvote r/singularity thread's top replies are the obvious counter, that none of this has shown up in Outlook's bug count or in how Microsoft still interviews.
