Considering the current rate of technology advancement and the political situation around the world, I think that there is no way our civilization will make it to the year 2100. I have thought about this a lot and I just cannot imagine a scenario in which civilization is not totally destroyed before then. And if civilization is not totally destroyed, I think it would be so insanely different than it is now that it would scare us out of our minds if we saw it. Sorry for being so cynical. I have not been watching sci-fi films or anything, I have just been thinking about things I have learned.
