The world is full of great tech. Why are people so miserable?

The world is full of great tech. Why are people so miserable?<br><br>A few weeks ago, I was driving to visit my brother in a small town in China. I saw a lady standing alone at the crossroads, looking anxious. I thought to myself, "If there were more traffic lights here, she would not be so anxious."<br><br>But then I thought about the city where I live. We have more traffic lights than anywhere else in the world. The roads are always crowded, and people are always in a rush, honking horns and scolding each other. We are more efficient, but we are also more miserable.
