Technological progress, just like a child's emotional development, is something that is resistance dependent. Our Tech has advanced so far in the last 100 years because we have had hostile forces of equal strenth to struggle against, before this the most a group of people (country, whatever) had to worry about was their next door neighbor. As communications and transportation tech grew, our world got a whole lot smaller, making all technology on our little rock in space pretty much the same all over the world, and also opening up the world for new enemies to make war/conflicts against. To combat each nation, a country had to develop their tech faster than anyone else (ie neccessity being the mother of invention - in this case, innovation). As time went on, this tech went from advanced to commonplace, and the visciuos cycle would begin again.
Now take the Nephilim, a hive race that only expends as much energy as possible (optimum) to complete a task. The Nephilim fight race after inferior race, conquering, not races they could learn from, but races that are vastly unprepared for Neph tech. Now, if they are beating opponents without much effort, what need would they have for upgrading their weapons? THey have no equal to oppose them, ie make them better. So no resistance = very little technological advancement. they don;t need more advanced weapons, so why spend the energy building them?
This is the scenario I use when accepting the Nephilims lack of advancement.
