Author here. 100%. Most recruiters are terrible, and they're kinda set up to fail because the data isn't there in exactly the same way.
The difference is that good human recruiters can make some meaningful warm intros, let 2 engineers get in a room together to see if there's chemistry, and get the hell out of the way.
I should make this clearer in the post. "Recruiters can't do hiring... and neither can AI. Both can't because the data's not there."
