Books maybe, but aren't people watching more movies than ever?
The thing is, they're also watching a smaller slice of the movies produced than ever...
It's not theaters, between Netflix and piracy, there are tons of more movies consumed. And whole TV-series, binge watched series by series, each of which amounts to 5+ movies running time...
While there's arguably been an overall shift to shorter content, I don't really see a marked falloff in movies being produced.
But that’s not the good stuff. For the good stuff I turn to 18 hour audiobooks, real movies, deep technical articles.
Bite sized for staying in touch, long and in-depth for things that interest you.
Then I watched "The Foreigner", yup, same old revenge plot.
I don't think I could study something difficult with Audio Books or any noise, but for example, tinkering or life's chores like washing clothes, emptying dishwashers, hoovering, showering.... These tasks which must be done anyway can become secondary to an audio book which takes the prime brain space to the point that those tasks become "enjoyable". Especially if you find a good book!
