Are 90% of them the sort of people who were terrible at English and History in high school?  Did they study math and computer science in college because those were the only subjects where they had any talent?    Did they then become professors and write utter rubbish that people are nevertheless obligated to read if it happens to be relevant to their field?     Do they deliberately substitute verbosity when a terse phrase will suffice, just to appear more pompous and authoritative?    Is there any real subject about which it is not possible to write clearly, concisely, and completely, with a Flesch score above 30?

I've read papers in other subjects, and none of them are as badly written as scholarly articles in Computer Science.
