I don't know about YOUR generation, but I have faith in MY abilities, and those of other Gen X-ers.
If we did it this time, we wouldn't have to learn how to fertilize crops using dead fish, and we wouldn't have to compete with an indigenous people for resources. With the technology available today, it wouldn't HAVE to be any more inconvenient than camping out, until it was better established.
The notion of 'terraforming' would come into play where extraterrestrial colonization was to be attempted. (unless you were gonna live in orbit.)
Personally, I am drawn to the idea of a floating colony, acting as a financial center, and with aquaculture as a significant revenue generating activity.
Popular Science explored that idea several years ago to some extent, and it didn't sound too outrageous to me. After establishing a floating, or underwater colony, space colonization would NOT seem too hard to undertake.
Humans need big dreams and goals.
Do people die TODAY for the defense of America and the dream that America provides, even in it's current Collectivist subverted condition??
So you will have no enemies? How unique.
