Yeah, taking those as one's examples is the equivalent of judging the medium of film by watching YouTube "brain rot" videos. "These were a waste of time and I didn't get anything out of them". Well, yeah. That entire genre (I'm back to treating of self-help and pop-business and "surprising" pop-science books) is infamous for being all but entirely garbage, defying Sturgeon's usual "90% of everything is crap" and achieving something more like 99.9%—and even that may be a generous assessment.
