Comparisons of social media to alcohol and tobacco are apt, it is something that's both harmful and difficult to quit. Rock music and books are not similar.

The issue isn't rock music, or dancing, or books. It's an older generation claiming that the way that they experienced things is better than the way the the current generation are, and they're worse off for it, and the younger generation just need to take their word for it (which is exactly what the commentor I've been replying to keeps saying).
Now, obviously rock music and books probably have less addictive design than social media, but it's still true: Once it starts negatively impacting your live, it becomes a problem.
