The rsync disaster proves AI isn't ready for infrastructure code

Short summary

A Claude-assisted commit introduced a critical regression in rsync, the timeless Unix tool quietly handling backups and deployments across millions of servers worldwide. The core problem: AI assistants lack any understanding of code criticality—they treat a weekend project the same as a thirty-year-old foundational utility. The solution isn't banning AI from infrastructure, but implementing risk-proportionate guardrails and enforcing paranoid-level review for critical code.

• •Claude-assisted patch caused rsync regression affecting global infrastructure
• •AI lacks understanding of code criticality and implicit user contracts
• •Need risk-proportionate guardrails, not a blanket ban on AI use
