To me, a work of art or a story created by a human will always have more value than something churned out by a machine.
"it is something that we should never devalue."
not sure when that come into the equation? People have been creating crap before generative AI. It seems to me like the author doesn't like the process of creation using generative AI techniques. For some people, generative AI allows them to express their art. So, there you go.
Humans will continue to produce valuable art, with or without generative AI. Until a computer and the brain are indistinguishable, the expression of thought will be valuable in it of itself. I think, therefore I am. We are far from having "thinking" machines--whatever that may even be. We don't understand consciousness and the goal posts for what is AI / AIG keep moving.
With that said, we know what the end-state may be. Singularity for instance, would be a game-changer.
While I think that "singularity" is just wild-eyed fantasy, if it ever happens then that will be the point at which humans are extinct.
Also for writing, even today you don't really know if an author has used a ghost writer to help them.
True, but the odds are overwhelming that the ghost writer was human.
But, yes, that would be an option. Honestly, though, if this sort of future actually comes to pass, I think I'll have much larger problems to find ways to handle first.
