The vileness of hoping people suffer aside, anyone who doesn’t have adequate testing in place is going to fail regardless of whether bad code is written by LLMs or Real True Super Developers.
What vileness? These are people who are gleefully sidestepping things they don't understand and putting tech debt onto others.
I'd say maybe up to 5-10 years ago, there was an attitude of learning something to gain mastery of it.
Today, it seems like people want to skip levels which eventually leads to catastrophic failure. Might as well accelerate it so we can all collectively snap out of it.
The mentality you're replying to confuses me. Yes, people can mess things up pretty badly with AI. But I genuinely don't understand why the assumption that anyone using AI is also not doing basic testing, or code review.
