Well, that may be what it was coined to mean, what does it mean now? Stochastic = statistical, parrot = using training data.

"a metaphor that frames large language models as systems that statistically mimic text without real understanding". I suppose you're defending them as having understanding. It's not "safe to say that argument has collapsed utterly", you're part of a campaign to reject the meme. On the other side, the meme is popular as a way to be rude about AI, because it's a cutting insult.

> what does it mean now?

It means whatever you want it to mean, that's the best part. To me, it's best used as it was intended, but primarily in the contexts where the stochastic parrots are plowing through the ivory towers we built mostly for idiot savants.
