A lot of people seem to like to believe that humans are being taken care of by a higher, superior force (e.g. God). I feel these thoughts arise from the average person's absolute disbelief in the idea that we have to take care of ourselves. Most people (even those who don't believe in God) feel that we are incapable of doing so. And I really cannot blame them for thinking like that...
But assuming that no great prophet or saviour turns up on this planet, the question remains... what will happen to us 10000 years from now?? What about 100000? The thing is that humans have existed in a civilized fashion only for the last 5000 years (although if you meet some of my friends you would think that is not true). And it took us that long to realise that we need to take care of ourselves and we need to work together to do so; Im referring to the establishment of agencies such as the UN; or previously the league of nations - we work together now in theory atleast.
Obviously though; despite the fact that some humans individually have a reasonably quick learning curve; the collective human race seems to be a very slow learner.
But even learning slowly might be good enough, as long as we do learn. Most popular economic, political and social thought now a days seems to believe in the principle of survival of the fittest - e.g. capitalism implies having a free market where the most competitive (or fittest) companies will survive; democracy implies freedom of political & social viewpoints where the political party with the most relevant agenda (again the 'fittest' in some sense) will gain popular acceptance and come to power. And thus, many people seem to be content in the idea that evolution of our thought and our society will continue as per this framework and we will keep getting better as a species. There seems to be an overwhelming belief in this quarter of the populace that in the long run humans cannot go wrong because survivalism will ensure that obsolete schools of thought will keep getting eliminated.
I am compelled to agree from the above theory, putting aside the possibilities of some extreme scenarios, that we should continue to evolve or atleast survive indefinitely into the future; because atleast this framework allows us to learn from our mistakes (however slowly that may be).
And thus we are now compelled to look into the extreme scenarios that may suddenly end our survival. Why? The study of the course of evolution gives a good reason - the dinosaurs. For a major portion of the existence of this planet the reptiles seemed to be kicking everyone elses asses and if any impartial alien observer ever landed on planet earth during the triassic period, he/she (or it) would have been convinced that the reptiles were the future. After all they had made it this far and were evolving within their race as well.
But then suddenly, the reptiles got screwed over when suddenly a meteor came down and annihilated the surface of the earth. I can actually imagine how when one day the dinosaurs were celebrating their survival thus far and their survival into the future as well (like humans do right now); from all the things that were possible, a
meteor came and ended their race. They must have been really dissapointed, some of them must have certainly cried 'foul play'.
The thing is that we cannot simply trust the theory of evolution to just take its own course and believe that we will continue to survive... random events can kill us all off any time (ask any dinosaur). So maybe humans will not have all the time in the universe to stay alive, and the same greater force that decided to kill the dinosaurs using the meteor attack, decides to get rid of the humans someday, thereby ending our course of evolution...
Coming to the point; my personal predictions on what the future will hold for humans (considering possbile extreme scenarios that can end the normal course of our evolution):
1. A meteor hits earth and kills us all (like it most probably killed the dinosaurs). Also human attempts to pull off the 'Armageddon' type rescue attempt fail miserably because Bruce Willis has died by then. Cockroaches, rats or other small insect like creatures take over the planet and study humans at some point in the future like we study the dinosaurs.
Probable time of death of the human race: Any time after Bruce Willis dies
2. We survive all meteor attacks but screw this planet over so badly that there aren't enough resources left to support a large population. A small section of humans still survives on limited resources before planet earth gets destroyed by the collapse of the sun.
Probable time of death of the human race: 5 billion years from now (the predicted collapse of the sun)
3. We screw planet earth over, but also find a way out of the planet & start to colonize other planets (or moons) in the solar system and eventually other parts of the galaxy... We thus minimize the risk of our race ending due to meteor attacks or collapse of the central star of each planetary system. We survive till the universe ends or we land up between the Alien Vs Predator conflict.
Probable time till death of the human race: 42 billion years from now (where the assumed big crunch might occur)
4. In the above scenario, a meteor hits each of the planets we colonized at precisely the same time.
Probable time till death of the human race: Again, any time after Bruce Willis dies
5. A long time ago, in a galaxy far, far away; Darth Vader built the death star as per command of the evil emperor Palpatine. They test fired a few shots into what they thought was empty space, and unfortunately one of those shots was unknowingly aimed right at earth.
Probable time till death of the human race: Depends on how far 'far, far away' actually is
6. Some stupid kid wanders into the pentagon by mistake and launches the entire barrage of nuclear weapons the US holds. A nuclear war follows and in the following nuclear winter all humans die due to extensive exposure to harmful radiation.
Probable time till death of the human race: Anytime soon; some stupid kids have already made it to the white house
Ofcourse the religious people could be right as well; now that I think about scenario 6 above, we most probably did not make it this far on our own merit and we do have a greater force taking care of us. Either way Ill most probably die at some point as well anyway, so I guess I don't have to worry about this topic too much...
