Why AI won't rewrite the OS: decades of accumulated edge cases are the real moat
AryHHAry · x · 2026-10-31
A discussion on software moats in the AI era: gadingcoder argues AI can generate features but struggles with edge cases accumulated over decades in Linux/Windows, long since caught by regression testing. AryHH extends: the real moat is machine-human interaction trails validated against hardware failures, concurrent access, security exploits and long-term entropy — not generatable from scratch with prompts. Bottlenecks: edge-case data is expensive/proprietary (some hardware discontinued), AI is strong at generation but weak at continuous verification and systematic regression, and reliability demands long-term auditability entangled with physical hardware. Software gets cheap, but trustworthy systems under real-world disturbance stay expensive.
