Not at all. Seems output in this brave new AI era is more or less the exact same as it was in the dark ages. The only output that has gone up, logarithmically at that, is spam and other low effort fodder.
I also want to push back on the idea that content is "solved." Consider the fact that you could be born in 1810 or 1910 or 2010 and in each of those eras, have more content available for you to read than you could ever read in your lifetime. People tend to enjoy contemporary stuff vs exclusively reading classics, and therefore there is constant demand for new stuff of quality in principle.
I think writers who are trying to become truly gifted writers aren't going to be out of demand in the future. I mean after all, technology has come up with dozens of new ways to commodity just about every medium of art there is for mass production, and yet, for every medium of art there is there are still sought after and celebrated artists.
Provenance has value. That is something that technologists often forget coming from engineering backgrounds, where everything they interact with is commodified and provenance doesn't matter at all, only the binary of if the spec is met.
