I don't read. However I go on walks and listen to an hour long podcast or an audiobook the entire time. Audiobooks and podcasts are continually growing in popularity. Is this somehow worse than reading?
Nothing wrong with listening to podcasts or audiobooks per se, but it's nowhere near reading when it comes to fruitful interaction with a source of information, and to transmission of knowledge. Written/printed/digital text is the biggest, most important invention, ever.
It's so deeply ingrained in me that this is something you do not do that it feels like sacrilege or blasphemy when I see books that are defaced like that. It's not exactly rational, but it's almost impossible to shake at this point. I don't think even my college books have a line of highlighter in them, although there's more than a few sticky notes lurking.
And for all those driving cars they’re also a huge win.
