However, my opinion is the current AI/chatGPT/LLM/whatever is a turning point for humanity. This is not propaganda. It is a technological breakthrough (or at least that's how it seems to be from my standpoint).
So far it's been a turning point for people committing plagiarism, fraud, political influencing, advertisement (particular in real estate) and other such areas where truthfulness isn't much of a concern. It might become a turning point for authors of fiction and other creatives, if legal means cannot protect them.
Waters are muddled and there's a
lot of money at stake, just looks at Nvidia's stock prize over the last year.
This judgement is based on the fact that it's very similar, if not identical, with how a human mind works.
*cough*, *cough*
"Deep" Neuronal Networks resemble a
model of how some think (or thought) the human mind might work. There are certainly other models (some suspect quantum mechanical effects play a role -- I would be surprised, if that wouldn't be the case). I think it's fair to say, that we don't know how the human mind works, until we can faithfully emulate it. So far we just realize how easily humans are fooled.
Just imagine you have mechanical work did by machines since industrialization age, then the Internet, then the AI that can think just think like a human, except it can read and know the whole human knowledge at once. If that's not a turning point in human race evolution, I don't know what would be. 
That would be, but we're certainly not there and I don't expect that we'll get there in our lifetime.
