Are all LLM research papers nowadays 100+ pages beasts?[D]

Was reading some research papers put out by Anthropic (and some other organizations/researchers) and one thing I've noticed is that these research papers consistently all share the same quality:

• Oftentimes over 100 pages of pure words, interspersed with screenshots of very dense/hard to read prompts and replies. Extremely-dry writing style.
• Oftentimes almost zero math or even math symbol to be seen.
• Uses some proprietary model with specific versions.
• Seems like a lot of work to (even want to) try to replicate their experiment.
• Discusses very subjective (and boring, at least to me) matters such as LLM emotions or introspections.

Who are these papers even written for? Certainly nobody is sitting down to read 100+ of subjective interpretations for a model that's barely accessible to the public, right? There are assigned readings for highschool english classes that are shorter than these papers. It seems to be a huge effort now to even check one of these papers for correctness or to formulate some thoughts around the paper. Just very confused at the state of LLM research.
