Automation/AI causing huge social and economic changes which destabilises nations across the globe.
Again this is gonna happend at some point.
Society will collasp when robots are able to do any job, better than a man (which again is just a matter of time).
At that point, only those that own robots, will make any profits.
Societ and our economy will have to undergo drastic changes, or see everything implode on itself.
(ei. captialism doesnt work, if the value of a human life working, is nothing)
^ this isnt something likely to happend in our lifetime though. I'd consider this something in the far future.
I think we will reach a point in our life where most jobs we do nowadays can be done by machine. That alone will be destabilising, and I think part of the political shifts happening in developed countries is because of this phenomena. The next decade will demonstrate this problem.
