I was thinking about this just yesterday with a slightly different spin. Many of my own conveniences are either wasteful, bad for me or bad for others. Sometimes they are even not so convenient. When technology works, it’s often great. When it doesn’t, it can be a huge time waster and a frustration. There is an old song with a line I always liked: “people don’t do what they believe in, they just do what’s most convenient, then they repent”. From The Guardian.
