People will be die in large numbers, but it will happen out of sight. It’ll be “soft genocide” or “malign neglect”, and the victims will be the climate change refugees who are kept out of sight by virtual walls. On land there may be fences and minefields and debatable ground dominated by gangs, and at sea there may be drone-patrolled waters where refugees can be encouraged to sink and drown out of sight of the denizens of their destination countries. This much we already see. But the exterminatory policies will continue at home in the destination zones as well, and that’s the new innovation that is gradually coming online. There will be no death camps in this shiny new extermination system. Rather, death by starvation and exposure will be inflicted by the operation of deliberately broken social security systems (see also universal credit), deportation of anyone who can be portrayed as an un-citizen (the Windrush scandal is an early prototype of this mechanism), and removal of the right to use money (via electronic fund transfers, once cash is phased out) from those deemed undesirable by an extrapolation of today’s Hostile Environment Policy and its equivalents.

You don’t need to build concentration camps with barbed wire fences and guards if you can turn your entire society into a machine-mediated panopticon with automated penalties for non-compliance.
