Timing is Everything

A question that comes up now and then, in discussions of more-or-less related topics like flying saucers, SETI, and the golden age of science fiction, is: "Where is everybody?"

Aliens by the Bushel

Science fiction of the first part of the 20th century often had people - not humans, indigenous people - living on Venus, Mars, Jupiter (cut them some slack, Jupiter might have had a solid surface), Saturn: even Mercury, Neptune, Uranus and Pluto were occasionally peopled with more-or-less plausible alien races.

Many of whom looked an awful lot like us: longish torso; hind legs almost half the total heel-to-head's-crown length, lined up with the torso; feet with a well-defined heel; two forelegs coming off well-defined shoulders, head at the end of a short neck.

Sure, some of them had bat-wings, funny-looking eyes, and weird complexions: but some makeup, an overcoat and an oversize hat, and they could walk around New York City without attracting all that much attention. Okay: maybe San Francisco or Los Angeles.

Aliens? Ain't No Aliens Here

At the other end of the spectrum there's Asimov's (original) 'robot' and 'Foundation' universe, where there weren't any aliens at all. Later writers came up with a variation on that, since we don't seem to like the idea that we're the only ones here.

But, that could be the way it is. That exotic-but-familiar universe of earlier sci-fi may be just wishful thinking. We could be the only people who have ever been living in this solar system, this arm of the Milky Way galaxy, or anywhere in the universe.

Considering that we're not selling souvenirs to, and performing colorful native dances for, tourists from the more well-to-do worlds of the Galactic Empire; or slaving away in the lint-mines of Evil Overlord Squig's Unified Worlds; there is a distinct possibility that we're it.

On the other hand, there may be people who are a whole lot smarter than we are, and who don't bother to travel: physically and openly.

As a character in Walt Kelley's Pogo said, whether it's just us, or we're at the low end of the intelligence scale: it's a sobering thought.

We Meet the Aliens: And They're Us

An intriguing variation of the 'crowded universe' scenario would be a setting some tens or hundreds of thousands of years ahead. Humanity set up shop on Mars, built orbital habitats, found its way to the stars, decided it was worthwhile to terraform Venus, and by the time of the story's 'now' there are aliens out there: exotic, strange-looking people - who are as human as you and I, but whose ancestors haven't been near Earth for quite some time.

Then, there's the possibility that we've already been to the stars. People who were essentially like us were around during the last major glaciation; the sea level was a lot lower then, exposing a great deal of the continental shelf.
Earth Was Not Always As It is Now
Think about it: Many major cities are on or very near the coast. Civilizations - the ones that we know of - grew for the most part along major river valleys. During the last major glacial period, major rivers still ran down to the sea - but the shore wasn't where it is now.
Gone Without a Trace
Somebody pointed out that a civilization equivalent to the one that bankrolled the Columbus expedition could have existed during the inter-glacial period before the one we're in - and left no obvious traces of its existence.

You can go further than that. There's been speculation that the last ice age ended fast, with continental glaciers melting and sliding into the ocean on a scale of weeks or months. If that happened, a thriving civilization's cities would have been flooded and sunk beneath hundreds of feet of water - with only a few survivors, who were near enough to boats and savvy enough to get out to relatively calm water while the getting was good.

Even if the seas rose slowly, it wouldn't have been good for any civilization. Think the worst-case global warming scenario, and multiply it by a few factors.
Atlantis? Sure: Makes a Good Story
No, I don't think there was something like our stories of Atlantis. No fantasy-cities, wizards, and all the rest. Still, it would make a good story.

I do think, though, that we don't know all there is to know about what we call 'prehistory' - the period before the civilizations we're aware of started keeping records outside their memories. There's a detail or two about the Sphinx in Egypt, for example - but it's getting late, and I need my sleep.

Nanotech and Keeping Up

Technology is changing rapidly just now. A very cool term, "nanotech," is being used - and misused - quite a lot. I put together a list of posts relating to nanotechnology, for another blog today. Here it is, with the post I created it for included.

I think the post titles give an idea of what gadgets might plausibly be used in stories set in the 'near future.' For anything more than, say fifty to a hundred years out? I don't think I'll be trying to describe how the technology works - just what it does. And, try to make sure it doesn't resemble a clunky version of something being developed this year by some outfit in Japan or Silicone Valley.

From Apathetic Lemming of the North: By the way, as I pointed out in today's post in the other blog, " 'Nanotechnology' Doesn't Mean 'Kinda Small'."

Food, Agriculture, Technology, and City Folks

Back in 1969, writing a story about how everybody would be starving in the immediate future would have been really, like, relevant.

These days, not so much: but some smart people don't seem to have gotten the memo.

I'm most of the way through a book, copyright 1990, by a fairly well-known science fiction/speculative fiction writer. It's well-written - and, just as important, I like the author's style. I'll probably be 'studying' it, later, to see just how the author achieves the tone and mood. And then adapt techniques I've learned to my own writing.

On the other hand, this author - remember, I like the stories - gets on my nerves now and again.

A Digression - Expectations, Assumptions, and 20-20 Hindsight

It's not the author having "the Soviets" still running Russia - and being a world power - in a fairly distant future.

20-20 hindsight is unfair. That little mix-up the Soviet Union had in Afghanistan, and a 600-kilometer-long chain of protesters demanding freedom (August 23, 1989) didn't make the headlines all that much.

The Soviet Union collapsing in 1991 or 1992 (depending on what milestones you use) probably came as a huge surprise to many people who had never lived in a world without the worker's paradise.

Like I say, 20-20 hindsight is unfair.

Speculative fiction writers don't, I think, 'predict' so much as extrapolate something they see - or think they see. For example, a timeline I'd been playing with involved the "Holy Soviet Empire" being a fairly active force a hundred years from now - I might still use that, as a sort of 'alternate history' story. But I doubt it. ("Holy Soviet"? I'd been watching the durability of the eastern Church in Russia - and what appeared to be an increasing realization that religion wasn't going to be stamped out - and came up with some hokum based vaguely on the Holy Roman Empire.)

Food, Agriculture, Technology, Malthus, and Opportunistic Omnivores

I've run into a description of homo sapiens sapiens that called us opportunistic omnivores. One phrase stuck in my mind: 'the first impulse a human has, seeing something new, is "I wonder what that tastes like?" ' I think there's something to that.

There are a few creatures on Earth that we can't eat because they're poison to us - and more that we can eat, but can't digest, like most parts of a tree. For the most part, however - although we do have dietary preferences, which vary radically from one culture to another - we can get nourishment from just about anything we can arm-wrestle down our throats.1

The rather more dignified way to put it is that, for most of the time humanity has been on Earth, we've been - ah - hunter-gatherers. There. Doesn't that make it sound better?

That was then, this is now. About 8,000 years ago some maniac had the crazy idea of taking seeds from plants he and his group liked to eat - and not eating them. Instead, he (or maybe she) planted them and took care to see that no other creature got at the plants first.

The idea caught on - and the human race was doomed. (See "Agriculture as a Mistake," Apathetic Lemming of the North (October 29, 2007))

Right now, we're about a thousand times over the 'carrying capacity' of Earth for our species. Like I said, we're doomed.

We can get by, I'm told, for a little over a month without eating - provided we get plenty of water and oxygen - so I figure that right around November 4th or so, 999 out of every 1,000 people will die: all around the world.

I should probably write a book about it. Some dude named Malthus wrote a book about 200 years ago, saying that irresponsible people were having babies faster than farmers could raise food - and we're all gonna die.

He took a lot longer to say that, and used bigger words - but that's the gist of it. And yes, I'm being a trifle unfair to that particular serious thinker.

The point is, this Malthus made quite a name for himself, by pointing out a terrible disaster that would doom humanity.

It hasn't happen, but his followers are still hopeful.

Wait a Minute Here! Let's Have a Reality Check

That 'thousand times over [delicate] Earth's carrying capacity' is a rough approximation - based on data which I haven't quite finished verifying. Statistically speaking, though - I'm right.

Humanity is doomed.

Civilization is going down with the scrubbin' bubbles.

And we're all gonna die.

Well, that last is almost certainly true: Given time, each human being dies. But seriously? I don't see a rapid increase in the rate, any time soon.

You see, that '999 out of a thousand will die' is based on the assumption that we all practice hunting-gathering.

Which we don't.

And haven't, most of us, for almost ten thousand years.

But if we did - and were living as opportunistic omnivores with tools that made us competitive with coyotes and wolves - Earth couldn't possibly support 6,000,000,000 of us. Each family group of us needs too much land.

So - we're doomed?

Not hardly.

News Flash! Human Beings are Clever

I think that people who are convinced that 'we're all gonna die' - from Malthus to a butterfly expert named Paul, to today's crop of doom-criers, have all missed a subtle, but important, point.

Human beings didn't stop being clever in the upper paleolithic.

We've got a long history (and a longer pre-history) of changing the rules.

Like, 'it's dark and cold at night.'

We don't like being in the dark and cold.

We figured out how to make fire.

Sometime after that, we figured out how to put out fires.

I'm not saying it's all beer and skittles - for example, not too long ago we found out why it's not a good idea to turn off the pumps in a nuclear reactor. Remember Chernobyl? Some of the 'fires' we're learning to put out these days are pretty serous.

But I don't think that people are any stupider now, than they were when someone invented string, or Archimedes got credit for inventing a helical water pump.

You Mean, Farmers Don't Look Like That? Well, Sha-Zam!

Reading that (very entertaining) book, I get the feeling that the author has something in common with quite a few of America's self-described best and brightest.

They haven't a clue what a farmer looks like.

I often get the impression that members of congress, and the 'experts' they listen to, have a mental image of what a farmer looks like that - how to I put this - is alternatively accurate.

He's got a slight posture problem: stands and walks with a slouch. Nothing serious, but noticeable. He wears dirty denim bib overalls, sometimes with a frayed straw hat, occasionally wears shoes - and sometimes has a shirt on. A flannel shirt.

He talks funny, and his intelligence is somewhere between that of an average reality-show contestant and a rutabaga.

If you asked America's serious thinkers to describe a 21st-century America farmer - jump-starting their frontal cortex in the process - America's best would probably realize that Joe Farmer doesn't pull the plow himself, or use a horse - and knows how to read and write.

Actually, the hayseed stereotype isn't all that far from the way (some) farmers dressed - in the warmer parts of America - maybe a century ago. And still do, when weather and work demand it. They do, however, wear boots. Farmers work around and in some very big, very powerful, machinery: and they need to keep their feet more than most office workers.

I think one of the problems that 'intelligent, sophisticated' people have is that, like just about everybody else in America these days - they're city folk.

I don't have anything against people who live in a city, or in the residential areas huddled around cities. For economic reasons, most people need to live close to - or in - cities. That's the way it is right now.

It does seem, though, that city folks - even if they've flown between cities - really aren't all that knowledgeable about what it's like outside the metropolitan areas. (See "The Effect of Information Technology and Media Preoocupation with Urban Events on the Relative Sophistication of Urban and Rural Populations ," Another War-on-Terror Blog (April 13, 2008))

The point I'm making is that, despite commonly-held (and, I trust, unconsidered) beliefs in America and quite a number of other places in the world, people don't have to practice agriculture the way we did a thousand years ago.

One of the big, recent, changes was the "green revolution" in the 20th century. If you're not directly or indirectly involved with agribusiness, you probably haven't heard of it. It doesn't fit the 'and we're all gonna die' model - and good news like that hasn't been relevant since sometime in the sixties.

Based on the fossil record and a few thousand years of recorded history, I doubt the "green revolution" is the last gasp of human ingenuity. These days, we may be more likely to build cute dancing robots, than something of more drearily serious merit: but I don't think we're all that much less bright than the people who figured out how to make tools out of flint.

And no: I don't think that 99.9% of humanity will be dead by mid-November.

Privacy Policy

Nothing spooky here.

These days it's important to have a "privacy policy" available: so here's mine.

I do not collect information on individuals visiting this blog. If you leave a comment, I'll read what you wrote: but I don't keep a record of comments, apart from what Blogger displays. (In other words, the only record of what you write or who you are will be what people see at the bottom of the post.)

I do collect information about how many hits this blog gets, where they come from, and some technical information. I use the WebSTAT service for this purpose - and all that shows is which ISP you use, and where it's located.

You can stop most of Webstat's data gathering by disabling cookies in your browser. I don't know why you would, but some folks do.

I'm also an AdSense affiliate, so Google collects information on what I've written in each post: but that's mostly my problem.

I'm also considering starting an affiliate relationship with DAZ Productions. You should be able to keep DAZ and Commission Junction, their provider of affiliate services, from collecting information by - again - disabling cookies in your browser.

And you can keep DAZ Productions from finding out anything about you, by not buying any of their products.

Again, I don't know why you would: but some folks do.

Or, rather, don't.
