These things are biologically/neurologically caused. They're adaptations that worked well in our ancestral environment (effort -> reward = satisfaction, stress = effort) which are now possibly becoming maladaptations. We won't be the first organism to experience this (likely unfortunate) transition. What's concerning is that it usually precipitates something bad like large genetic alterations through natural selection or the simple elimination of the organism from certain environments (like fireflies near cities).
