>Maybe for resume cover letters and LinkedIn posts but I haven't met anyone with half decent taste who prefers AI writing, even well prompted, to skillful human writing.
That attitude is one, maybe two generations away from extinction. Taste is created by the market, which caters to the young. When enough people have been born into a world in which AI generated culture and communication is the norm, that is what will define what good taste is. People like you (and I) will just come off like old people yelling at clouds.
We can already see this happening at the fringes. People have relationships with AI, they prefer AIs to real people, they use AI as a primary source of truth, they consider AI generated art to be superior to human work, they trust AI more than people. People identify as AI. AI is filling an emotional, sociological and creative space that an increasingly alienating and hostile society denies to people, for better or worse. Generative AI has only been a thing in popular culture for four years or so and it has already completely transformed human society and human sociology.
Barring a complete collapse of the AI bubble, which seems existentially impossible at this point given how invested our economies and government are in it, that's just what normal is going to be in a decade or so.
There's taste and then there's taste
Popular taste is guaranteed to be awful since it is driven by economics and fads. That's the type you point out as created by the market and catering to the young. It's a disposable product of consumption used to sell shoes and overpriced paintings.
I don't disagree that it will permeate everything, it already does. It'll just be written by an AI instead of people being paid to find the next style to cop. I don't think it will extinguish human writing, you'll just have AI writing that you feed to official or public channels and then real writing that goes in private or pseudonymous channels. Using AI writing among friends or an in group will still be a faux pas and cringe because it will have become the norm to be rebelled against.
