This is a valid point, but it's referring to the state of things as of ~1.5 years ago. The field has evolved a lot, and now you can readily augment LLMs answers with context in the form of validated, sourced and "approved" knowledge.
Is it possible that you are having a visceral reaction to the "cool new tech" without yourself having been exposed to the latest state of that tech? To me your answer seems like a knee-jerk reaction to the "AI hype" but if you look at how things evolved over the past year, there's a clear indication that these issues will get ironed out, and the next iterations will be better in every way. I wonder, at that point, where the goalposts will be moved...
