I’ve got to admit, starships are intriguing, as is the idea that someone can build a largish skyscraper with a fusion generator in the basement, and that building will contain a village-supporting ecosystem (powered entirely by the fusion generator) and also be missile-proof. On the bad side, this vision seems a bit, I don’t know, silly perhaps? The skyscraper, I mean. That’s effectively what a starship is, though, and existence of one implies the other.
On the other hand, we can assume the obvious answer for the Fermi Paradox, that the reason we haven’t heard from aliens is that starships are logistically impossible, even if they are possible under the laws of physics. This comes about simply because starships require so many breakthroughs in so many fields. A failure to achieve any of these breakthroughs–power plant, shielding, compact, human-supporting biospheres (or stasis, or computer upload systems that last for centuries), and keeping the crew together for the duration of the voyage–dooms the starship. All of them could be impossible.
At this point, some SF aficionados throw up their hands and scream “therefore we’re all doomed! The Earth won’t last forever, and humans have to.” This is foolish. Yes, of course we’re all doomed to die, one way or another (sorry if this is unwelcome news), but Earth has another billion or more years to run before it becomes uninhabitable, and it’s quite likely that humans on Earth have another few million years before we go extinct, no matter how stupid we are.
The basic point here is that humans will almost certainly survive a transition from our current, fossil-fuel based, economy to one that is not based on fossil fuels, and the only reason I say “almost certainly” is because I’m currently reading Legacy of Ashes: The History of the CIA, and cringing how many attempted suicides the US unknowingly avoided. Anyway, the point is that people will survive, whether we decide to end our dependence on fossil fuels by crashing civilization, or whether we get to innovating and finding ways to do more with less, just as we have for untold centuries.
What will that future look like? In some ways, it will look like the starship future, at least for the next few centuries. As we get nine billion people on the planet, we’re going to have to find ways to feed more people with less land and water. Given how much we currently waste, this may be possible, if not pleasant.
–Oceanic fishing will largely disappear for centuries. There are so many anoxic zones already that it’s likely that most people will give up fishing, and ships will have to carry all their food with them. I’ve had fun imagining a future Pacific where big, ark-like windjammers travel among the islands, all the food grown or shipped with them and fresh water recycled aboard as much as possible. The islands that survive sea level rise may start to resemble the self-sufficient dome cities of the previous post, since they’ll be less able (or entirely unable) to draw on the sea for their livelihoods. This is a grim thought for those of us who admire the old Polynesian cultures, but fodder for any SF writer who wants to re-imagine the old idea of asteroid belt colonies out in the Pacific, with kite-sailers replacing singleships. Anyone want to mine lava for precious elements?
–Farming will change. We’ll probably start recycling sewage onto farmland (if only to recapture the phosphorus, since we’re running short of mineable sources for that essential element), and we’ll certainly eat less meat. We’re already getting a powerful taste of climate change, with those record-breaking heatwaves and storms, and it’s going to get worse. We’ll have to get used to the idea of crops failing, and we’ll have to get very good at storing food during the good years. Currently, big agribusiness has a lock on both the food economy and politics, but that may fail suddenly, if the few big companies that dominate the Ag industry fail to deal adequately with crop failures, changing climate zones, and other problems. Rural America has been “dumbed down” for most of a century, with the bright kids lured into the cities. We’re facing a time when we need really, really smart farmers. I suspect we’ll get them, and this will affect both agribusiness and politics. Personally, I hope that permaculture takes off in a big way, but that’s because I’m an ecologist and I think it’s cool.
–Politics: It’s amazing how much politics in the US is affected by air conditioners. If the amazingly complicated US power grid starts to fail, people are going to start migrating north, out of current red states and into the blue. Some people say this is what’s driving the current Republican party, and they may be right. America is getting less white, and throughout much of the world, we’re seeing smaller families. There will be a gerontocracy for the rest of our lives, I’m afraid, but after that, who knows? We’re so used to thinking of political economy as growth that it will take innovation to face a future where populations decline.
I could go on, because this is the kind of future that makes more sense to me. Perhaps it’s because I’m a pessimist? Or is it that the idea of human history having millions of years of one damn thing after another is actually more appealing than centuries of adolescent style, unlimited growth? For SF writers, there is good news here:
–there are plenty of Apocalypses to go around. If we really do live for millions of years, we’ll see the end of the fossil fuel age (in the geologic near term), the end of global warming (as I posted on a while back), at least one more ice age, multiple Carrington Events, asteroid strikes, devastating earthquakes and volcanoes, east Kilauea sliding into the sea and inundating the west coast, dogs and cats living together, and so forth. I was toying with the idea of starting an SF scenario called “after the 34th apocalypse” set waaaay far in the future, but I would have had to figure out what all 34 apocalypses would be. The point would be that the end of civilization as we know it might become old hat after a while, with coping strategies and everything.
–Many futures are possible. Given a combination of limited resources and humanity’s incredible capacity for ignorance, boredom, and self-delusion, I predict that people are going to try most options repeatedly. Everything from slaughterhouse dictatorships to drop-out wannabe utopias will appear again and again. Modern giant agribusiness isn’t the first time western civilization tried huge agriculture (see latifundias), and it’s certainly not going to be the last time, although I’m sure we’ll see periods of small farms in the near future. Dictatorships will come and go, and there will always be a new religion popping up somewhere, even if most of them don’t survive much past their creators’ lifespans.
–Science will always be around. It’s common knowledge that most of the world’s current great religions (Christianity, Buddhism, Taoism, Hinduism in its current incarnation, and Islam) were created during the so-called “Axial Age” of empires in Rome, India, and China. They and their descendents are still around, in massively altered form. We’re centuries in to another age of global empires, and I’ve been wondering what new form of religion will come about. The answer was so obvious that I almost missed it: science. History is accretionary, not cyclical. Although Christianity is monotheistic, it early on absorbed a whole body of saints and pagan holidays from the old religions it replaced. Islam and Buddhism did the same thing, and I think the trend is universal among missionary religions. Because of this, I’m pretty sure science won’t go away either, no matter how hard people try to suppress its inconvenient truths. It’s so embedded in all of our lives that, like the notion that God should be capitalized, it’s not going to go away. Science *will* change radically in coming centuries as it subsumes arising cultures, but people will keep doing it. When we go through future ages of upheaval and global empires in coming millennia, our descendents will likely come up with still other “religions” that fundamentally change the way we think. I wonder what they will be?
–Domestication will rule much of the world. As with ants and termites, the human species’ fundamental adaptation has been domestication, which I like to describe as a massive campaign of symbiotic adaptations. While we can live without agriculture, I don’t think we’re going to do so. It’s simply too useful. Rather, I think that evolution is going to continue to take advantage of our domesticated ecosystems, just as it is doing right now. We will see more pests, pathogens, and parasites (including social parasites), and they will only get more sophisticated through coming centuries. I’m quite sure our counter-measures will get more sophisticated too, in a coevolutionary arms race, and I suspect that agriculture in, say, 40,000 years, will look radically different than it looks today. Farm ecosystems will be much more complex, and much of that complexity will be outside human control. Fortunately, I don’t think wilderness will ever entirely vanish, either.
–Similarly, I don’t think machines are going away, and I think that the complexity of mechanized ecosystems will only increase over time. I also think it’s likely that domesticated and mechanical ecosystems will merge more thoroughly than they have already.
In other words, there will be grim meat-hook futures, but I suspect that for every grim meat-hook generation, the next generation will make the best of things, get on with life, and be relatively happy. Things could be worse.
