AI is basically the Status Apocalypse for the intellectual class. Look closely at the different viewpoints crystallizing, very few will last another 12 months.
Pangram will not work for much longer, or it will cost thousands of dollars. Slop is a technically solved problem but it's not evenly distributed yet because highbrow prose has tiny economic value relative to coding.
Uniquely stylish and powerful prose will still command a premium, but the best prose writers of the next generation are going to do that WITH AI (to variable degrees in many different production configurations).
Nobody whose identity, status or income derive from highbrow prose production wants to say this aloud because it means that all of their social worth and much of their self-worth is now up for grabs. Of course, the best writers today are well positioned to be some of the best prose engineers of the next generation, but they'd have to reinvent their way of thinking and working, which established careerists resent having to do.
The other big issue that contemporary writers resent is that, in the AI era, to be a "good writer" will require that you have real truths that other people don't have. And you're going to have to take risks to express them. Today, you can hide the lack of these two things with sufficiently advanced erudition and style. The people most freaking out right now are the fancy wordsmiths with fancy positions who have no real alpha and no real courage. It is absolutely rational for them to be stigmatizing AI unconditionally.
(The only reason I can say this aloud is that I've walked away from a successful academic career, so I've already traversed my status collapse voluntarily. I now feel pretty immune to whatever humblings technology has in store for us...)
