If job-seekers were using bots to spam their resume to every job opening, whether they fit it or not, if they were creating resumes that didn't actually fit their talents (lying), and if companies were advertising openings that didn't actually exist, then the true job seekers and the true job openings can't find each other in the sea of lies and spam.
And, from what I can gather, that has been increasingly true for a decade. I don't know whether AI has made it worse in the last few years.
