This fascination with "new worlds" as a major source of hope or inspiration in the world is a relatively recent concept and an almost exclusively Western one. It’s also one inextricably linked to imperialism.
I completely disagree with the first points. I think you're confusing an impulse with the ideological baggage that has accrued around it, particularly in the last five or so centuries. Our earliest literary heroes--characters like Rama, Gilgamesh, Odysseus--were travelers par excellance; their stories mapped known and speculated-at worlds, horizontally across the Earth and even vertically into sacred geographies. Alongside religious texts, the travelogue (and sometimes both in one), in content if not generically, is a theme of incredible antiquity. I'm not aware of any period in western history for which records survive that did not manifest this longing for a better world (of which, really, a number of religions, western and otherwise, could also be said to represent). I am, admiteddly, not as well versed in other cultural traditions beyond the formative stages of civilization, but migration and colonization (and even imperalism) are not Western-exclusive phenomena. People may have migrated often for material/economic reasons more than genuine desire for exploration, but it wasn't often viewed that way, particularly if the competition for resources back 'home' (wherever that may be) manifested itself along ideological lines. To seek a better world does not belong to any particular place or time.
Aligned with imperialism, that I can't contest. But the negative consequences that have followed on our exploratory efforts do not invalidate the need to find in the first place.
(On the litany of things worth discovering - we haven't discovered a way to have a decent standard of living while actually preserving the biodiversity of our planet, or how to educate people well enough that they don't beat the hell out of their kids, or how to reign in human greed that runs so rampant we can barely run a business that treats their staff humanely - so I think we have a few more frontiers to "conquer".)
None of that is anything that can be discovered, only worked at (unless the discovery is some form of neurological programming).
Look, I understand that we're all in a post-modern malaise that results from living under a dead paradigm that has been hideously transmogrified from new worlds to explore to new products to consume, but I really find this angst to be very teenagery. So we have no new paradigm at the moment - let's fucking well get busy figuring one out. Because sitting around in our funny glasses longing after simplistic fantasies thought up by someone else isn't doing us much good. (...) But I also find exotic worlds every day in the inner lives of the people around me, I find challenging adventure in the problems in our world that need solving, and I find the awe-inspiring unknown in art and spirituality. In the end, the real world beats fantasy any day of the week - because it's not safe, or simple, or perfect.
I'm not saying not to act. I've nothing against it, provide it doesn't wind up doing more harm than good. (The problem is, of course: whose paradigm? As long as we can't agree on that, we'll always wind up at cross-purposes, sabotaging each other--religious fundamentalism being the prime example.) But action doesn't mean we shouldn't recognize the causes, shouldn't try to identify what's wrong in the first place. And we must also recognize that it is possible that there's no solution, that these things we choose to imbue with importance to give ourselves a meaning in an otherwise meaningless world--family, causes, fantasy worlds (religion)--are merely shields against whatever absence you may wish to source the malaise to, a way of deflecting our attention away from our impotence and futility. And what you find 'stimulating' in reality, others may not.
