This is what I was thinking the other day too. One one hand, all the effort and team work people are doing is causing technology to progress rapidly, and therefore making our lives more comfortable, but on the other hand, the never ending fierce competition we face and the higher skills required for jobs, is taking a toll on our emotional and physical health. Rather than making people happier, this is making them more stressed. So, technological progress is a kind of double edged sword. Maybe decentralization and sharing economy is gonna help more people to be self employed, and thus make them happier. Lets hope :)
