Maybe in 10 years we can blame poor reading comprehension on having a decade of computers reading for us. But it’s a bit early for that.
We have a multitude of immediate distractions now.
Books build richer worlds & ideas. But without learning to love books very early in life, which takes a lot of uninterrupted time, they don’t come naturally to most.
I used to read a few books a week, virtually every week. Sometimes two or three in a long day and some night. I still read a lot daily, interesting and useful things in short form. But finding time to read books seems to have become more difficult.
