What do you think the future on Earth will look like in 100 or 200 years?

Consider the earth 150 years ago as a midpoint -- 1863 was the year. Swords and horses were still mainstays of war. Construction didn't exceed six stories. Human flight was fantasy. People generally didn't travel faster than 30 miles per hour and live to tell about it. Antibiotics had not been conceived of. The most advanced medical procedure was crude amputation. Political enfranchisement was withheld on the basis of race and gender. Instant communication over long distances was restricted to Morse code and was mostly unavailable. Video did not exist. Music could not be recorded. Cities could not be incinerated in seconds.  If someone of 1863 said, "2013 will be just like today but with automation and a different economic standard" (Venus project) or, "2013 will be just like today but society will have collapsed into anarchy and cannibalism" (The Road), his prophecy would be inadequate at best. The advances and changes are too numerous, too profound, too bizarre. So too for us; it's impossible to describe the year 2163, because we do not have words for the things of that world. At least we know they will need energy, matter and information and they will have an easier time of getting them than we do.

We cannot predict the distant future anymore than they could 150 years ago, so while my view is obviously wrong, some tendencies should be right provided there are no catastrofic global events changing everything :-) Info processing will not be dominated by unassisted human brains. Integration between brain and tech will be ever increasingly close. Distance and hence nation states will become increasingly irrelevant as information flows are global and can simulate a face2face meeting adequately including touch for the romantically inclined. The limited size of Earth will be of ever increasing importance. Atomic weapons, hole in ozone layer, global warming, are but the first signs we are reaching global limits. Medical advances will change the fundamentals of being human like life span, health, aging, strength, stamina, looks, sensory input. It will be hard for ppl to imagine living under our awful conditions. Just like we don't get how it was to have a life expectancy of 40, no dental hygiene, illness everywhere, regularly see your kids die, experience famine regularly, etc. Economic conditions will improve facilitated by greater productivity of better tech. Absolute poverty will be eliminated, while relative poverty will increase. Aspect of technology will be like magic, others will be familiar. Just like ours is to somebody from 1850. I think we will reach space, expand into the solar system. Ppl will still be unsatisfied with the political process. Still be worried about crime. Still experience economic crisises regularly. Still trying to improve their social status. Still be unfaithful. Still debate religion. Although from an increasingly abstract and intellectual view point as the need for prayer gets less immediate due to less hardship. There will be artificial entities that we can hardly distinguish from human and it will creep some ppl out, while others couldn't care less. The trend towards increased specialization will continue. Ever increasing the diversification of human experience, making it both harder and more interesting to get to know new people. The complexity of life and society will continue to increase. And much more... Lol

There is a excellent web site called Futuretimeline.net dedicated to this very subject,using a combination of science fact and fiction.....  From their web site .. Welcome to the future! Below, you will find a speculative timeline of future history. Part fact and part fiction, the timeline is based on detailed research that includes analysis of current trends, long-term environmental changes, advances in technology such as Moore's Law, future medical breakthroughs, the evolving geopolitical landscape and more. Where possible, references have been provided to support the predictions. 100 year prediction http://www.futuretimeline.net/22ndcentury/2100-2149.htm#AI 200 year prediction http://www.futuretimeline.net/23rdcentury/2200-2249.htm#global-rewilding

Actually, despite what many people would think, making a decent prediction (educated guess) on what the world would look like isn't entirely impossible. Thanks to the internet and media, many new technologies that would otherwise be confined to a small community could easily be broadcast/unveiled to millions of people in a blink of an eye. With that in mind, I'll throw out a few potentially/possibly interesting development in the next 100 or 200 years: 1. With the advancement of 3D-printer, many household item can be created in your own home, tailored to your own needs/design; this may leads to a decline in domestic good industry, especially so in simpler product (i.e: cups, fork, decorative items, etc). A new industry will arise to supply the raw material for various 3D printing. 2. With the refinement and development of space colonization technology; there will be an increase interest in exotic properties (space, underwater, sky, etc). Followed by an increase in various related protest/lawsuit, and various new medical condition resulting from prolong exposure to exotic location. Though many would fail without without a proper development plan. That is the first two potentials/interest that comes to mind, I might add more if I thought of something.

Within the next few decades, climate change, crop failure, resource wars and migration will destabilize most economies, which will then mostly revert to subsistence agriculture.

A Huge population reduction due to the unsustainability of   7  to 11 billion people once the oil is gone. We are coming to  the end of the  OIL AGE - probable within the next 30 years. So forget 100 to 200 years the parties over. Prior to this period the world could only support a population of less then 1 Billion - so do the math. The only probable survivors will be remote tribes that live in some of the Rain Forests of the world.  It is estimated that there may be 70 or so such tribes that we have no knowledge off and have never confronted Modern civilization living in the Rain Forest of Brazil. Completely self reliant and not a single IPhone or Facebook to get them through the day.
