> I did not have internet or tv as kid and I have learned a lot from books.

Growing up in a TV-free household as a kid was and still is an advantage to develop learning skills, independence, and imagination.

> Now I have internet, and I spend far more time on social media and watching shows than I spend on learning things

That may be, but you have the choice.

The main difference is that you can find way more information than in books, even if you lived in a library. The main problem on top of the continuous distraction is curation.

Isn’t this general kids vs adult things? I think most (but not all) people learn less and less as they get older.

For practical, “try at home” things, internet is just making everything so much better. You can read books a lot, but if you want to learn how to make a laser from scratch (for example), no book will be nearly as good as a bunch of blog posts and forum to connect to others.
