Today’s “typical” writing style.
The paragraphs are in repeated short “sound bytes”. Sentences are repeated on the web sites in different colors and fonts for “emphasis “ and “eye stopping” highlights.
Because the public can’t read anything longer than one sentence.
There was a recent article about young people who “read for fun”. That rate has plummeted recently for people at about age 9. And I believe that statistically, children who stop reading for fun by age 10 or so just never really start up again. So the dip that is currently happening basically means adults in 10+ years will have almost no interest (or ability) to read anything meaningful.
