I had read and appreciated Cole's article (and his other works as well).

Here's my slightly extended take: Screenwriting is always a give-and-take between the familiar and the new. Too much familiar = an unenjoyable story for most viewers because it's trite / boring; too much new material = unenjoyable because it's outside the world of the audience--"unbelievable" to their minds.

From what I can tell, the prodcos are looking to AI not to replace writers but to shrink the pool of writers in a room (and to speed up the development process). AI, as I understand it, can only act as an adjunct insofar as it rehashes what's already known. In other words, an AI-assisted story will provide producers with what they think is a profitable outcome (the familiar), but it can't anticipate the unfamiliar / the new. If you think the major studios are dependent on Marvel franchises, just wait until they start repurposing every cliché from every film ever made.
