one question spoiler altert
what good does it do to destroy the "device"
they must have blueprints for it and programming code and the developers are most likely alife.
they could build the device on Area 51 tomorrow if they wanted too.
they destroyed a piece of hardware but the design is stored somewhere.
as a computer person I just think that way.
if they wanted it never to be used again they should have destroyed the blueprints.
