I’m not in disagreement there! AI is troubling—especially when we speak of curation—but I think there has always been a tension between solid, high quality poetry and faddish poetry whether the curators have been publishers (again I point to Rod McKuen in the 1970s) or AI.
Even so, good poetry has never made money (most poets make their living doing something else)—bad poetry has—but only because the marketing was better. Twenty, thirty, fifty years later you can’t find those books (bad poetry), but the solid work is still published.
Side note (and not something you’ve mentioned):
Others have commented that judging Instapoets as bad poetry is an exercise in classism (those poor Instapoets against snobby professors). In my opinion , the pop poets and Instapoets tend to have more than enough funds to market themselves—(compared to humanities professors who do not make near the money people think!) so, talk of classism is way off the mark.
