I understand that, the point I'm making is that reliability is not a requirement for utility. One does not need to be reliable to be reliably useful :)
A very similar example is StackOverflow. If you copy/paste answers verbatim from SO, you will have problems. Some top answers are deeply broken or have obvious bugs. Frequently, SO answers are only related to your question, but do not explicitly answer it.
SO is useful to the industry in the same way LLMs are.
Sure, there is a range. If it works 100% of the time its clearly useful. If it works 0% then it clearly isn't.
LLMs are in the middle. Its unclear which side of the line they are on. Some ancedotes say one thing some say another. That's why studies would be great. Its also why syntax highlighting is a bad comparison since that is not in the greyzone.
