Can't read the article. Does he mean it's a problem in search of a solution then? Or does he mean it's "the exact opposite of a solution, in search of a problem" (in other words, a problem in search of a problem)?
And that's why I personally don't have much faith in the LLM approach. Natural language is too full of ambiguity to pretend it delivers meaning. It makes oblique references to meaning, based on awful assumptions about the audience and presumed mental context.
I see enough absurd miscommunication and word salad between native speakers. I really don't want a magic box to vaguely emulate this.
