Any eng that is only using Claude Code or Codex or whatever, is frankly not entitled to talk about AI's limits since they are using the most basic harnesses. They literally don't know better.

When I see Claude Code or Codex users on HN talking about how coding with AI is risky, it's like watching someone that has only ever seen a catapult argue about how space travel must be impossible.
