I look for what comes
after "the key here is ...". Indication of where the key lies means nothing to me if the key is nowhere to be found in a video/article. "Ceci n'est pas une pipe".
Most content is useless mostly not because of malice, but simply because people who put content about what interests me mostly never have worked on actual real world projects. They'll write about experiment tracking and ML project management and will just snatch the marketing brochure of whatever library pushed out by some company at a summit, never having used that library for actual work, heck never having run the getting started, to notice the cracks. They'd have relevant content if they had. Oh, well. Nobody "got time" for that, need to churn out a Medium post/YouTube video.
