If the criticism can't distill up from "bad things could happen", it just isn't useful to keep paying people to come up with that kind of critique.
And it isn't like we stopped paying attention to these concerns, is it? Nor were they completely blind siding us at the time. The question was largely of what to do about them.
The question also whether large-scale utilization of LLMs (and also the prerequisite increased training processes) should proceed before these issues were addressed. Clearly, we collectively answered "yes" without any actual reasoning (and arguably, without any collective decision making either).
It’s pretty common in the security world to have a red team and a blue team. There is overlap in the skillset for both, but there are good reasons to have separate people develop each team, and we wouldn’t expect people to have a talent for both.
Ideally, we like it if the red team can suggest solutions, but that’s not always their job or expertise and I’ve rarely if ever heard someone express the sentiment you are within that context by suggesting a really good red team person isn’t useful if they can’t fix the holes they find.
