Because we haven't got it yet. As I said earlier, the backstory not being in the game yet doesn't actually reduce the amount of backstory much, it simply shifts the effort to the player, and each player will see that differently. I see it as a contradiction, you don't. Fair enough. That is why I added a poll, to get an idea of the distribution of opinions.But why bother? I'm not a dev, surely it's up to them to develop the back story as much as they do the coding and art.
I am not saying that it has to be done either. If the Devs decide they don't care or that it doesn't matter then I'm fine with that, but no decision had been made yet as they weren't aware that it might seems contradictory to some of their players. Similarly, if the story and world lore is to be later worked into the game somehow and that lore will explain it away, then I'm fine with it remaining as it is, as that would itself define the technology more precisely.
