I would agree with the sentiment of the commenter though. Software bugs in proprietary software are real, but LLMs tend to overstate their criticality, and/or inside knowledge is at times needed to exploit those.

We've sure seen that LLMs can make good assumptions about blackboxes and, unlike humans, are able to try many paths in a short time. However, one can't neglect that doomsday prayers have been present before the dawn of AI, and rarely companies got hacked.

From anecdata, the human is still most often the culprit for breaches, not the "We managed to penetrate that one byte often enough" exploit.
