Basically, Echo is a nymph that was condemned to never be able to speak her own words, she can only repeat back (portions of) what people say around her, hence what we call an echo.

Just like LLMs / AI are not able to create something new, just regurgitate based on the content they were trained on (our own).

Echo falls in love with Narcissus, who rejects her, and this bum falls in love with his own reflection in the water.

I posit that we humans are Narcissus having not rejected Echo, and instead fell in love with her.

We fell in love with her/ai because she/ai says what we want to hear, and those are the words we tell her.

I always thought of Delphi's Oracle when seeing people assuming intelligence behind periods composed with human-sounding wording.

Funny thing is that to have the "mistery" in the Oracle's words you needed to "stone" a woman to the limit.
