I think the author might agree that they never will exist, but because of his actual point about what they will do to creative work and communities, not any physical limitations.
I think it is still a solid argument, especially when juxtaposed with anything related to developing something new and innovative, whether in the domain of arts, science, or business. But what I found insightful in this quote was the note about the least predictable things.
The market for 'fully tech driven' content exists, sure, but it'll always just be that.
The examples I always think of are Kurt Vonnegut and Raymond Carver.
Vonnegut's experience in WWII heavily impacted his writing and views, and led him to create one of his best works.
Additionally, when I talked to a war veteran about Slaughterhouse Five he said that the time travel was very relatable. When he came home, he felt like he was moving backward and forward in time. Everything at his home was the same, and it was like he never left. It was such an interesting conversation, and something that made me appreciate Vonnegut so much more.
For Carver, I just really enjoyed learning about his life. His work experience, personal relationships, and experience with alcoholism shows up in almost all of his stories. I find it cool to read a story, and draw parallels to his life.
Additionally, my father was a blue collar worker and worked in many different jobs his entire life. I draw so many parallels from the stories he's told me to Raymond Carver's stories.
I really love forming connections like this to the art that I enjoy.
There's a strong historical pattern that the appearance of the limits of reason has always been due to a lack of imagination, often in the very people who just spent their lives expanding its borders. And these arguments so often rest on "je ne sais quois," it comes off as more ridiculous than parsimonious. If you think you found an illogical or indeterminate system, I'd bet that your body of kmowledge just needs reframing.
Though ever further we might see, surely dragons further be! c:
Using your metaphor at the end: "There's dragons just over the next hill" and "There haven't been dragons so far so there will never be dragons" are both just guesses.
Wouldn't that just testify that Hollywood et al. are no longer really "innovating"?
Which is why, as a creative, I'm not super-worried about AI destroying creativity. It might actually help democratize much of the tools one needs to make a movie or a book, but at the end of the day creative consumption is a human-to-human demand.
