Some Uncomfortable Truths About AI Coding Agents: 35 CVEs in March, $380/Day Costs, 3-Month Wall for Vibe-Coded Projects

Standup For Me / Hacker News·medium signal

A practitioner blog post (72 points, 85 comments on HN) lays out specific failure modes of AI coding agents: at least 35 new CVE entries in March 2026 were directly attributable to AI-generated code (up from 6 in January), daily AI coding costs have reached ~$380 ($91K annualized), and vibe-coded projects consistently hit a maintainability wall around three months. The high comment-to-point ratio (1.18) signals strong practitioner debate about the real costs of AI-assisted development.
