The disproportionate rise of the machines, they're here for our jobs, they've been taking them for years but they won't take them all soon enough.
People dream of a futuristic utopia where no one needs to work as machines will do all our jobs, but we'll never get there.
Soon driving will be another thing they do and we don't, that's not just those that drive for a living (taxi's, truckers, bus drivers etc..) but associated industries, filling stations, truck stops, car manufacturers (though not gone, significantly scaled back due to less demand when you can use a "jonny cab" over ownership) - then they'll take the pilots, the trains (hell, some trains have already been done).
It will get to a point where a large percentage of jobs can be done by machines, my job is developing software that will largely make my department redundant.
But not all, and they'll be too many of us for the jobs that're left.
You think your average cabbie can retrain to be a surgeon (for however long that profession last as machines are working their way into that)?
There will be wide spread unemployment, meaning massive civil upheaval and eventually a humanity revolt against the machines plunging us into a new dark age.
Unless we have some sort of terrible disease break out to dwindle the numbers.
Or we reach the tipping point where AI can take all jobs and we can all be unemployed, free to do as we please.
But even that is unsure, people in power use wealth to be there, their power is bolstered by their bank account. If we reach a utopia we won't need money, their power will not be so great, that doesn't sound like something someone has devoted their life to achieving will give up easily. I don't think they's allow us to achieve utopia, better to keep the cattle in line - but then what do they do about the mass unemployment..
