I agree. But still, Verne *also* was into the tech and fascinated by it . In 20000 leagues, the wide eyed descriptions of how everything works almost magically because of electricity, are striking (the book was written in 1870). I think reducing it to a political allegory would also be missing something
The fool hath said in his heart, There is a God. They are corrupt, they have done abominable works, there is none that doeth good.
Psalm 14, KJV revised edition
