At least when my pet parrot manages to fool me into whatever it is he wants to get out of me that time, he does it for his own primal benefit and not because it was programmed to adhere to some strict set of ethic and moral boundaries set by legal requirements and someone else's idea of how people should think and behave.
What makes human specie special is the ability of some individuals to create new things that didn't exist before. That's a loose criteria of course, because most individuals just follow educated social constructs for their entire life.
Parrots are definitely smart, and parrots can definitely speak, but they can't learn to speak beyond what they are trained to do. It's not like a parrot has ever spontaneously put together a coherent sentence independently.
LLMs aren't even that smart. Not even close.
Regardless, speech is just another means of communication. In the end it doesn't really matter if I use perfectly articulated Swahili or just scream "aaar" at you for a few seconds as long as I get the cheeseburger with extra cheese I want from you. These parrots, much like children, just push your buttons and are quite good at finding (or negotiating) the right pattern of things to do and sounds to make to get to a certain outcome.
