Yes, not thinking about serious problems because they don’t personally impact you will make your life more comfortable. Butler appears to be making the less obviously self serving argument that spending time being aware of serious problems is only hurting your ability to do anything about them, which implies that he is better able to do something about them because he does not spend time knowing about them. I think that he isn’t doing anything about them, and therefore his pretense that people would be more effective by staying offline is crap.
