All academic literature is specialist literature. If you aren’t trained in the field you likely won’t understand it. It’s totally reasonable to me that a STEM person would have no idea what this abstract is saying just as a Humanities person probably couldn’t make heads or tails of the abstract of a dissertation on category theory or on a particular branch of computer science.
I find it funny that STEM folks always go after humanities academics for being obtuse when its just a matter of the pot calling the kettle black—dense STEM research and theory uses language that’d be considered equally obtuse to the untrained reader.
