I think it was Switzerland or some other country where they're thinking of implementing a basic living allowance. Many things will be automated and performed by robots -- Conservatively, I say another 15 years before that process begins to snowball. It's been an interesting thought project of mine to imagine an entirely automated McDonald's restaurant. That said, machines are expensive to own and maintain...

Only corporations with access to resources will be able to control them. It's kind of worrisome, to an extent, but this would be a problem for government to tackle: If corporations own the machines, thereby removing the worker, to whom will the profits go? Who will be the ones buying cheeseburgers from McDonald's?

What would you do with your free time if you didn't have to work?

The only thing that would prevent a civilization like this from existing would be the greed and maliciousness of those holding influential positions... clinging to the past and fighting for breath like a dying candle. A system like this is inevitable, but it will require the awakening of the world's population; there's more than enough iPhones for everyone.
