If you see coworkers chatting over a coffee, do you think, "wow, they're being totally unproductive. They don't need those coffees, they should be working!"? Of course not.
Consuming _and discussing_ news is a social activity. If your life is your work and nothing else, you'd be a very boring person.
Consuming information by choice allows us to express ourselves later with our opinions. Everyone should make an effort to learn about their surroundings to be an informed, contributing member of a democratic society. People say politicians are out of touch, but compared to a lot of Americans who willingly cut off their exposure to news, are they really?
It's actually funny reading your post, because you sound exactly like me when I was your age. As you get older, I think you'll learn to appreciate relationships with people more. The 18+ hour startup days lose their appeal.
