I've been a space enthusiast since infancy. I'm an amateur cartoonist - first thing I ever drew was a Saturn 1B in crayola, but I had never more than a layman's interest in the knitty gritty soot-coated specifics of spaceflight until my mid teens. I browsed the site for a few years, got an account, and upgraded to a year's L2 last year.
Unlike a lot of people here, space never motivated me to be an engineer. I was obsessed by the idea that the godlike abilities of the human race are but a dusting of nitrogen from being amusingly pathetic, however much we pride ourselves as possessing dominion over the forces of the universe.
Our earliest mythologies concern humanity's interaction with time. What time does to us, what it does to the world, what the separation of time creates. We created societies based upon lineage and time, and for thousands upon thousands of years time was the only element of the universe worthy of study. People moved as fast as the horse could carry them, if they were wealthy. If they were not, they moved as far as their feet could take them. Most people didn't leave the ten mile circumference around their birth place, around their sources of food. Distance was interesting, but time, time regulated everything. The cycle of crops, trade, what ships would come into port and when, when it was safe to go to sea, when to wake and when to sleep. Michel Foucault, writing in 'Of Other Spaces (1967), Heterotopias', aptly observed that "The great obsession of the 19th century [and earlier] was, as we know, history". What had happened before an individual's life, more often than not, would determine the status of their life in the present. The "ever accumulating past" was critical to the human's perception of itself. Think of theology - most religions make a point that most prophecies have occurred, most prophets have existed, and all that remains is an (often predetermined) end of the world event. Man can no longer change the boundaries of reality. Aristocrats, slave owners and Emperors took their right to possess land (and people) from the fact their parents owned the same land and the parents of those presently bonded.
There is much to be said for having an old guard. Without generational ideologies, peace is impossible and we would live in total, undying anarchy as nobody agreed with anyone else on any subject ever. We could not exist as a species. There always have been mavericks, pushing technological mobility forwards, often resulting in social mobility as old, oppressive systems become impractical. Sometimes these futurist pursuits have negative results when they advance faster than the minds of the people controlling the technology - spears fly, gunpowder explodes, machine guns perforate, battleships sink, planes leave nobody to hide anywhere anymore, spy satellites know everything about you. Yet for every innovation that leads to violence results in hundreds to hundreds of thousands of positive applications. We have spectrometers, we have interplanetary probes, we have antibiotics, we have internal combustion engines. We can turn any surface on the planet into a cityscape if we just throw enough man hours into it.
With all these advances, time isn't quite so scary. We know how time relates to the universe, more or less. We know how to modulate our passage through time, how time is a horrifyingly complex tangle of micro-to-macrostructures moving at all manner of mindbending velocities. Our cities live in 24 hour electric sunrises. Time still concerns the average person, but it's the the great mystery anymore.
Before, we lived in a world with borders. Contrary to popular belief, people of Ptolemy's time and before knew that the world was round. Flat earther for the unenlightened was an insult even multi-millenia ago. For millennia people had been describing entities that could traverse through the celestial sphere in nearly every human culture, but the sky seemed a barrier reserved for beings with far longer lifespans than the average human. Individuals who could wield the power to destroy the world at whim, yet also had the power to be great creators, of the like mortality could not match. "The celestial place was in its turn opposed to the terrestrial place." Yet it didn't prevent people from exploring space and exploiting what they found there. When humans ran out of ocean and regolith in the 19th century, we'd already invented balloons and started going up. Drills got better, as did submarines, and we started going down. We were a three dimensional species, and started exploring three dimensional space.
We're now at a time when we are rapidly running out of three dimensional space. This is a ludicrous situation in a universe that (for practical purposes), is infinite in a possibly infinite spectra of multiverses. SpaceX gives a chance at meaningful exploration within my lifetime on a timescale somewhat more tangible than sometime in the somethingth recurring, and L2 lets me get my fill of free wish fulfillment. What's not to like?
Plus, I dig blue sunrises.
