Sure, some will read the random wattpad smut, or isekai royalroad story, or the random fanfic; but that's the equivalent of eating soda for dinner: feels good in the moment, bloats you up and it's completely devoid of any nutrition whatsoever. Also messes up the mouth and stomach bacterial ecosystem.
And so no one puts in the hours, nobody puts in the effort and dedication to build taste and to build the necessary mental stamina for difficult readings. To read becomes a very niche activity, like calligraphy, or drawing. A gaping hole widens in mankind's soul and there's nothing that would fill it up again.
