That's almost certainly what it was intended to beCould it be "cybernetics"? Was that a thing yet?
Yeah, the Fiends are distinctly a variation on Monsters from the Id; though their ability to propagate and need for neural tissue to live complicates the matter enormously. Well, at least they can be killed unlike the Id Monster.I just noticed that there's a parallel to Forbidden Planet here: both Walgate in FWAF and Morbius in FP are making mental monsters through the use of atomic power! In Morbius' case to keep his secrets to himself (with maybe some Freudian shenanigans concerning his daughter); in Walgate's case the monsters just express his desire to suck the knowledge out of other people's brains, maybe?
