An LLM isn't even a species. I prefer communicating with other humans, unless I choose to interact with an LLM. But then I know that it's a text generator and not a person, even when I ask it to act like a person. The difference matters to most humans.
I'm predicting the future a little with that. As always people accept new ideas at a glacial pace.
At what point do we consider some entity alive? At what point do we decide to consider it a species (of living thing)?
If we find out there are aliens, biological and therefore similar to us? Sure. What if we meet aliens whose physical forms are synthetic? What if we meet the synthetic creations of biological aliens?
I'm not saying that LLMs are alive, of course. But I am saying that I'd consider LLMs to be a precursor to AGI, along with all our our historical artificial intelligence experiments, in the same way that prokaryotes were the precursors to...us.
