I know I was a lot more productive when I didn't care about the news and didn't watch any TV shows. I don't think you are a functioning adult unless you know the major goings-on of the world. People talk about the news a lot and it's important for those interactions even if it is little more than gossip. I think swapping quite a lot of the consumption of the low-quality news with books and other hobbies is something we ought to all do and spend news consumption on the higher quality publications as a decent middle ground between cold turkey and continuous consumption of nonsense.
