One might argue that the boon of fossil fuels was actually the cause of a lot of chaos and war since the technological change it enabled was so rapid and norms around war took a long time to catch up.

The Second World War was mostly caused by the aftershocks of the first. Maybe if things had progressed more slowly, we could have avoided the upheaval.
