i dig the period the story takes place in. I think if kishi tried to have an industrial revolution in naruto and introduced things like cars and machine guns the series would flop. I keep imagining Naruto meets Fable 3... like children would be used for manual labor not trained to be ninjas lol and all the characters would have Brittish accents and wear 18th century clothes
and now that i think about the technology used in naruto i think its cool that they use chakra and sensory ninjas to communicate with anyone, anywhere in the world
