Depends. 50 years is a long time. Will there be a major conflict with a Western power? Will the wealth divide continue to eliminate any trace of the middle class? Will some of the proposed environmental disasters that people hypothesise about now be a reality? I think there's a whole lot of questions we don't really know the answer to, and if the 21st Century is anything like the 20th ... which is the only objective measure we really have ... then it might not be a technologically advanced Wonderland that people might romanticise.
In the last century we consumed half of the world's fossil fuels, and we are FURTHER away from feeding the world population now than we were back in the 40s and 50s.
For example, look at publications written 60 years ago hypothesising what was a futuristic image of the livelihoods we were supposedly to own for ourselves by the turn of the millenium, and that was back when we still had a thriving middle class. Technology increases only insofar as people wish to pay for it and make such technologies economically viable. The idea of the technological singularity assumes that there is the same amount of economic mobility then as if now.
If what we have seen from the 21st century is anything to go by, I expect that the USD will likely be replaced by basket currencies which may or may not be better for world trade depending on how peaceful the transition from one reserve currency to another. There's no way that the world can properly accomodate for the inflation that we've seen. Particularly given that were living much longer lives but ultimately our production per person is dropping far faster. If the 20th Century was the argument of labour vs. capital, this century will be the fight of capital vs. democratic systems. The problem is that both may not survive the ensuing chaos, in much the same way we had far too many close calls in the 20th century to massive collateral damage that would arguably be unsurvivable.
Of course that's not precluding the event by which we might achieve something better than both. Humans are remarkably resourceful when they need to be and they'll still be a whole lot of us come 2065 to mull over solutions to problems that we are too lazy to correct now. But I hold little hope that the 21st century will somehow be a safer, more prosperous century to live in than the last. There's nothing to suggest that we as a collection of cultures are anymore sympathetic, empathetic, or any more humane than those who lived and died in the 20th century. If anything, we're drowning in the problems of the world via mass media saturation and it seems to do little more than instill apathy. It may very well be a case where the ontological shock of the demise of human civilization will be realized only when the trigger has already been pulled.
Whilst this may seem an alarmist statement to make, consider the fact that you have scientists now (either rightly or wrongly) trying to shake the idea into us that the world is facing catastrophic ecological decay generates little more than a 'meh' from 99% of humanity.
(edit) Honestly, observing how security heavy, and how invasive various identification methods are getting ... including integrated poublic security devices that literally record all your metadata where you move, and what you buy, and your usual trip from home to work and back again ... then I kind of suspect that the Western world will likely go Gattaca. After all, it's cheaper to let security systems determine where all people are simultaneously and solve crimes that way than it is to have police merely patrolling about. I mean, look at Google ... it can literally build an effective behavioural profile on anyone that uses it on a daily basis.
So I suspect that divides in voter rhetoric and consumer choices will be predictable well in advance of any ballot box or initial public presentation of goods. Rendering the democratic process an exercise of targeted online advertisement and a mastery of behavioural psychology rather than any solid political philosophy in action.
