I find it quite amazing that the human race is progressing, in terms of acquiring knowledge, at exponential rates in recent years. Just a few decades ago, decent computers were the size of an entire room; mobile phones were only fictional items; we did not know very much about the universe beyond Pluto.
These days, powerful computers are very small and portable; people can surf the net via their mobile phones; and scientists are able to arrive at a learned estimate of the number of planets in our galaxy. Furthermore, they've estimated that there are 500 million planets in our galaxy alone which are potentially habitable. Amazing when you come to think of the scale of progress we've achieved within just the last 50 years!
If we can keep it going for the next 50 years—and I can't see why not—imagine how much more knowledge we would've gained by then. Although it's rather too ambitious, it's not impossible to send manned spacecrafts out to at least the planets within our own solar system. Who knows, maybe we would've progressed so far in genetic science by then to the extent that we're able to expand lifespan to a few hundred years for each human; which in turn can make space travel possible. Either that or we're able to invent very fast spacecrafts to cut down travelling time. In fact, it's entirely possible that geneticists could play around with the human DNA for a bit so that they could, for example, make the brains of politicians grow in the skull instead of the rectum. The way I see it, the possibilities are limitless!
But of course not all of us will progress so quickly. As I have said before, not all of us are born geniuses. Some of us are still preoccupied with our little world under the coconut shell; our visions are limited to the size of that shell. These creatures invest their time analysing seemingly petty matters, and then arrive at unfathomable conclusions. They see elements of Christianity in the poco-poco and deem the dance haram to the Muslims. Maybe they, too, can get some help from the geneticists I speak of in the preceding paragraph, I don't know.
