My brain: damn that's a big cactus

Take my upvote.

That's why I'd take the position of being cautious and waiting for better quality studies.

There really needs to be more studies done and then a meta study to really nail this down. Or at least some high quality well reviewed studies.

Just because people aren't reading books doesn't mean they aren't reading. I'm sure some people are just watching video content like TikTok or Youtube etc, but they'd have just been watching TV anyway.

People are reading, just not books so much.
