I agree. I recommend most people don't go overboard, but they can still do their part.
Save the things you like and are relevant to you. Movies, shows, games, music, books, etc. You don't have to be an archivist. Storing data should be something that reflects you, personally, and it should genuinely be more enjoyable as a result.
It should feel good to preserve and be responsible for another copy of the information you like.
