This is a massive problem in some circles I am in, particularly relating to early Christian history and theology. You'll find a lot of people who take photos of their books and use a certain kind of language typical to the area of study but they cannot actually summarize what they've read. They reduce books and learning to a mere aesthetic that lets them signal certain group affiliations, its an exercise in vain self-aggrandization.

It makes it harder, especially as a beginner in some areas, to find a good community where you can actually learn since for every 1 knowledgeable person who can help you understand and learn the material there are 5 others who know how to /sound/ like they know what they are talking about but are actually repeating buzzwords they gained from skimming entry-level secondary sources.
