Thematic issues. Why all the sci fi.

This will surprise you, but this is basically the state of the real life earth and a very accurate representation. Societies do not suddenly all advance to the same technology mostly because of politics, education, money and sometimes because tribes like to stay away from advanced society because that's what they chose to do.

The world is nothing like this. When two societies interact things change for both of them. Pretty much everyone has adopted cell phones and internet at this point. And of all things, transportation and weaponry are the biggest and fastest changes. You don't see any nation sailing galleons do you? Cars have been adopted universally, same with airplanes.

EVERYONE has moved on to guns.

This is all inevitable, because things, whether old or new cost money, and a government can't in good conscience keep investing its resources into obsolete technology so they can be conquered on a whim. As soon as new weapons are introduced changes come in fast and furious.
