It's really too early to tell what the long term impact of LLMs will be. I know it's new, and exciting, and so on, but we saw the same hype with VR, with 3D TVs and so on.
It's perhaps unfortunate that the high-profile one is made by a company with AI in the name. This is confusing media, and by extension, non-techies into into using the word "intelligent".
Sure these models pass a Turing test, and they write incredibly well, but they're not intelligent. They're basically a search engine with good grammer.
As humans we consider well-spokeness as a proxy for intelligence. How we mock those who speak broken English - they are clearly not intelligent. By contrast the well spoken person is clearly smart (even if what he says is bullshit to those who actually know.)
So here is a computer that speaks with excellent grammer. Clearly it is intelligent. Clearly it is out to rule the world.
The truth alas is less exotic. By scraping a zillion Web pages, and reading a zillion twitter feeds, it merely parrots what has already been written. Computers used to be good at math (once a sign of intelligence) now they are good at language as well.
Is this useful? Sure. There are lots of places where good writing is important. Is it the next wave of computing? It's too early to tell. I have my doubts, but that I'd likely somewhat fueled by the many waves I've seen on the horizon that were ripples when they got to shore.
