The location is actually in Europe, specifically the UK.In every country in the world? Or a select few? Cuz I'm guessing US. Shit always happens in the US and the fact that most average Americans can't get a proper health care and the average American longetivity keeps dropping lower and lower.So assuming we nuked ourselves in let's say WW3 then those must be the rubbles of the nuked cities and that nothing lived on it hence the built walls and the toxic environment. It takes years for life on a nuked place to go back right?
I would also like to know more of your predictions if you ever decide to take a peek into the future again. You're not the first person here that predicts or says a similar thing about a more benevolent future for humankind and I do think that humankind will correct itself when another world war happens because we're hard-headed that way so I think a benevolent future for us will happen after WW3.
I do see the near to medium future the divide between the rich and the poor becomes great, what we call the middle class disappears and homelessness becomes an absolutely huge problem, if you think we have problems today then 'today' by comparison would seem like a golden age. Due to it becoming such a big problem the homeless are demonised by the media and various laws are bought in to push out the homeless including rewards for reporting them causing many homeless to turn on each other for said rewards, it's a really sad mess.
