The bug is called "applying actual engineering principles and critical thinking".
The absolute vast majority of people who point out AI's downsides have used it and use it. People who uncritically write things like "I work at a big tech company and I don't know a single person that still hand writes code." scare the shit out of us for a good reason.
Using it is not enough. You have to explore its boundaries, see what it can do when cost is not a constraint. This is only really possible at the big tech companies and well funded startups.
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.
