I do hope they have some good explanation for the setting - tons of technology but they live in caves and wear animal skins?
Looks like maybe it was a design they built a story around, and not vice versa. If it's fun it doesn't really matter I guess.
I thought it was obvious from the trailer. Technology rebelled against humanity, so humanity's use of it is very limited. It's kind of like The Matrix, only the machines are actually trying to exterminate humans directly.
Yeah, but they still use mechanical objects like their weapons - they can't make things like clothes, housing, vehicles, whatever? Why not make airplanes and bomb the monsters instead of shooting them with crazy explosive arrows?
