``Physics behind precision'' at future linear or circular colliders (ILC /FCC projects) require imporved input parameters. I will review the role alpha_{QED, eff} at future collider energies and report on possible progres from low energy machines. Besides "what physics can be discovered" with such FCC-ee option, we also would like to understand better how nature works when energies increase.
