Yep, the year is 2238, not 2010. But maybe you forgot, that there was some, uh, great war?

Mutants were made after the war, robots got destroyed/weren't that important.
There were no robots who survived, atleast not for the average wasteland person we are playing,
the sooner you will realize this the better. That your are comparing Super Mutants with Robots is even more showing that you don't have anything to tell about the fallout world.
