So a long time since I've seen a few episodes of this, there's some new and so I watch them.
And - depending on where you live, have already come to pass.
Consider China, a very little bit in the news lately, still rioting over the Covid lockdowns, videos of massive internment ("quarantine") camps being constructed outside cities, videos of apartment buildings under quarantine having their doors welded shut, and "Code Yellow" - that app by default required on Chinese phones - that tracks where you've been and if you've come in contact with anyone suspected of having Covid turns yellow - the yellow advising you to report to quarantine for testing.
And - that app, it's needed to let you onto public transport, into shops, into your own apartment building. So - if it turns yellow or red, you're done. Just done.
So, watching what was only a couple of years ago some sort of dystopic science fiction right now playing out under our noses, only it's not here, not here yet...
Otherwise, some interesting predictions on a future that's already arrived...
