I'm not so sure about that. Put yourself in the shoes of a 1st century person describing the world of today. Even a person two hundred years ago would not have words to describe it, and it would be very hard to understand without those words. If we try to describe some thing that doesn't exist yet, we have to use words that already exist and approximate. Whenever I read Revelation I see it describing a technologically advanced world, just described with pre-industrial words, like for example in chapter 11, where 'all peoples' look upon the dead prophets. The only way this is possible is with instant communication and transmission.
Sure. Although if they are describing the modern world. They will use words "Great thunder and smoke came out of their hands"
"Like horses with breastplates breathing fire and smoke galloping along the ground". "Birds clad in iron dropped fire from the sky".
