In Agents of S.H.I.E.L.D. season 7, the team
goes back in time to 1931 in the first episode and meets Ernest Koenig, the ancestor of the Koenigs in the present-day timeline.
During the second episode, the team brings Koenig to the Zephyr, and un-blindfolds him, showing him the interior. He begins to freak out about the fact that he's on a "rocket ship". Then he sees Enoch, whose skin is torn on his skull, revealing his robotic head. Koenig then remarks:
KOENIG: This is one of those, uh, electric men, oh, oh, I know, a robot! Is that a robot?
ENOCH: I am not a robot. I am a Chronicom. If you'll excuse me, I must go fix my face.
Now, the episode is set in
the 1930s,
and it baffles me as to how Koenig knew the term. From what I can recall, the word "robot" wasn't used until the 40s or later (although I could be wrong on that), but even if the term was invented around then, it wouldn't have been used in a widespread manner (especially in America, since the term comes from the Czech language). Was Koenig's use of the term "robot" historically accurate for 1930s America?
