What all of you have to realize is just look around you. Technology is evolving at such a fast clip that by the year 2036 we will most likely have deep space colonie on the Moon & Mars (despite what NASA is saying today, they're just trying to minimize expectations).
As well the level at which new technology develops, doubles & triples every 5 years. Since every new development spurs even more advanced technology, the microprocesser is a case in point. Just look at five years ago compared to today.
In the next 5 maybe 10 years fusion (clean, non-polluting, non-nuclear, powerful) energy will become a reality, space based lasers that can propel rockets and destroy comets are already close to completion.
I'm thankful that I'm still young enough, that barring some unforseen circumstances in the next 20 years before I retire I will get to see incredible technologies far surpassing anything in the past 20 years.
I know, I'm a nerd, but I'm excited at the prospect.
