You adapt to deal with particular difficulties. When something new eases your life and eliminates those difficulties without introducing huge additional cognitive load, it does the same for everyone else, rendering your previous adaptation no longer advantageous—enabling competition may, in fact, indirectly threaten whatever you may feel like an island of stability in the chaos of life.

(It’s just one angle of looking at this, of course, it may not always apply, but it could explain counter-intuitive instances of resistance to change.)
