It seems like life is so short and insignificant: that as it stands we can only achieve greater purpose through numbers, or by passing our genes on throughout generations...
However, as time goes on, as does our understanding of technology, surely we will be overcoming these barriers: our very own consciusnesses will break free from the rules of old, and will begin to increase in importance and influence.
It seems like we're standing at a huge turning point, and that within our lifetimes there will be huge technological advancements; changes which will allow some of us to extend our lifespans significantly.
It may reduce the conflicts in the world; will allow us to travel further into space; will allow us to accumulate greater comprehenshion of subjects and further increase our scientific understanding; will curb the rates of reproduction, etc, etc. There will be huge knock on effects.
However, will all these be changes for good? What will be the adverse effects of a world population which lives 10 times as long as it currently does?
Then, what methods will be employed to allow us to live for longer? Will they be cybernetic, biological or medical? Will we transfer our consciousnesses to robots; learn to manipulate/rebuild our cells and bodies biologically or advance medicine to the point that nothing will ever knock us down?
