Douthwaite states that technological fixes are necessary to solve social problems. The other two authors would disagree with that on a certain level. In the language of Johnston, he believes that modern problems cannot be reduced to mere engineering solutions over long term because human goals are diverse and constantly changing. This makes sense because different groups of people have different problems and have different ways of solving things. Huesemann talks about scientific reductionism, and how scientific finds can actually hurt and create social problems giving an overall negative effect. That is how Douthwaite differs from the other authors on how technological fixes are necessary on solving social problems. All three authors give good points on what the cause and effects are on what technology does to the future.
Technological fixes to social and environmental systems have negative repercussions, because putting things out of equilibrium can disrupt our nature on how we act and approach things. Whenever humans in particular are put into disequilibrium, negative effects are certain to happen. What most people fear is what they know little about. However, this should not stop the flow of making technological discoveries, even if that means there will be negative effects. You could even argue that a discovery that has negative problems now, will eventually give light to problem in the future. In my mind, it makes sense to always look forward to the future without any regrets of the past. We wouldn’t have nuclear energy today without the scary advancement of nuclear power. You can’t change the past, but you can always improve on the future.
