What I feel has changed, and what drives a lot of the fear and anxiety you see, is a sudden perception of possibility, of accessibility.
A lot of us (read: people) are implicit dualists, even if we say otherwise. It seems to be a sticky bias in the human mind (see: the vanishing problem of AI). Indeed, you can see a whole lot of dualism in this thread!
And even if you don't believe that LLMs themselves are "intelligent" (by whatever metric you define that to be...), you can still experience an exposing and unseating of some of the foundations of that dualism.
LLMs may not be a destination, but their unprecedented capabilities open up the potential for a road to something much more humanlike in ways that perhaps did not feel possible before, or at least not possible any time soon.
They are powerful enough to change the priors of one's internal understanding of what can be done and how quickly. Which is an uncomfortable process for those of us experiencing it.
Absolutely spot on. I am not a dualist at all and I've been surprised to see how many people with deep-seated dualist intuition this has revealed, even if they publicly claim not to.
I view it as embarrassing? It's like believing in fairies or something.
