I don't think the mirror is a warning. It could be the most valuable thing LLMs can do for us. I recently dug very deep into my own use of LLMs and why I was getting different results than a lot of my peers. I think the primary difference is I look at them as a tool that can extract what's below my verbal mind, deeper in my experience and intuition. Everyone points LLMs outward, "go build this", "go write that", but they miss the most valuable thing, "help me get this idea out of my head".
I recently wrote a book about this, turns out the mirror is more interesting when you stop looking past it and look into it. And even more when you realize LLMs are not humans, they have strengths, and weaknesses, but so do the humans using them. If used carefully you can achieve much more together than either part can alone.
