Scratch another dearly loved sf myth

New research seems to show mordern human evolution is supercharged:

In a study published in the Dec. 10 issue of the Proceedings of the National Academy of Sciences (PNAS), a team led by University of Wisconsin-Madison anthropologist John Hawks estimates that positive selection just in the past 5,000 years alone — around the period of the Stone Age — has occurred at a rate roughly 100 times higher than any other period of human evolution. Many of the new genetic adjustments are occurring around changes in the human diet brought on by the advent of agriculture, and resistance to epidemic diseases that became major killers after the growth of human civilizations.

“In evolutionary terms, cultures that grow slowly are at a disadvantage, but the massive growth of human populations has led to far more genetic mutations,” says Hawks. “And every mutation that is advantageous to people has a chance of being selected and driven toward fixation. What we are catching is an exceptional time.”

The findings may lead to a very broad rethinking of human evolution, Hawks says, especially in the view that modern culture has essentially relaxed the need for physical genetic changes in humans to improve survival. Adds Hawks: “We are more different genetically from people living 5,000 years ago than they were different from Neanderthals.”

Science fiction’s dirty little secret is that it tends to believe in pseudoscience more often than it does in real science; even supposedly “hard” science fiction is littered with impossible or just wrong science. The idea that evolution has “stopped” is one of them, usually used in a setting which contrasts the brave manly colonists of Proycon B with the teeming soulles dependent masses ruled by an incompetent, corrupt bureaucracy of Earth. So much for that idea.

Cory Doctorow

I’m not sure I actually like Cory Doctorow, either as a blogger or an esseff writer. Boing Boing used to be on my blogroll until it got too up itself for me, and I’ve tried his fiction but haven’t managed to finish any of it. Part of what annoys me about him is his relentless self promotion, part his equally relentless, somewhat naive techno exuberance. The combination just sets my teeth on edge.

A good example was linked to by Making Light the other day, a short called “Other People’s Money“, which was written for Forbes. The excerpt below showcases what I dislike about Doctorow’s writing:

“You’d have thought I’d learned my lesson by then, but no, sir. I am the original glutton for punishment. After Bubble 2.0, I took my best coders, our CFO, and a dozen of our users and did a little health-care startup, brokering carbon-neutral medical travel plans to Fortune 500s. Today that sounds like old hat, but back then, it was sexy. No one seriously believed that we could get out from under the HMOs, but between Virgin’s cheap bulk-ticket sales and the stellar medical deals in Venezuela, Argentina and Cuba, it was the only cost-effective way. And once the IWWWW signed up 80 percent of the U.S. workforce through World of Starcraft guilds, no employer could afford to skimp on health insurance.
The word would go out during that night’s raids and by the morning, you’d have picket lines in front of every branch office.

The whole story is like that, one long infodump laced with buzzwords and jargon to show what Doctorow thinks could be our future. It’s near future and of a type that I should like, like much of Doctorow’s work, as it’s simular to what people like Neal Stephenson and Bruce Sterling have also written. There’s one great difference though, in that their stories were grounded in a political and sociological awareness that I find lacking with Doctorow.

Brasyl – Ian McDonald

Cover of Brasyl


Brasyl
Ian McDonald
404 pages
published in 2007

Call Ian McDonald the anti-Niven. Whereas Larry Niven has often been accused of writing all his characters as if they belong at an early sixties Californian cocktail party, McDonald’s characters always come across as belonging to the particular ethnic and cultural background they’re said to belong to. This is because McDonald, like the best science fiction writers is genuinely interested in culture as well as science, and genuinely interested in cultures other than his own. He has a knack for painting a picture of a given culture, whether real or invented, through the judicious use of background detail and character interests. So far I’ve not yet read a McDonald novel in which the world he created didn’t convince me. His latest novel, Brasyl, continues that trend. It’s set, of course, in that perpetual country of the future: Brazil.

Comparisons with McDonald’s 2004 novel River of Gods are therefore quickly made, though unjustified. Apart from that both novels take place in countries that are not often used as a setting in science fiction and apart from these settings being an essential part of them, not just an exotic background for some displaced westerners adventure to take place against, the two novels have nothing much in common. Which is just as well.

Happy birthday Sputnik

Sputnik 1

fifty years ago today the first manmade object reached orbit. Science fiction fans everywhere thought it would be the start of mankind’s thriumphant conquest of space, even if it was the Russkies who did it, but it didn’t quite work out that way. While we’re using satellites for all kinds of important stuff, that whole idea that humanity had to leave its cradle behind seemed a lot less attractive in reality than science fiction had made it seem — quite a lot harder as well. We’re struggling to get a space station capable of keeping half a dozen astronauts living there for a month or two up and running, let alone that we can get the million inhabitants L5 colonies O’Neill dreams up going. For now, the future seems to be Earth orbit satellites and unmanned probes to the rest of the Solar System, plus the occasional hype of a new Moon or Mars programme

Should we be disappointed with this? That we have no giant space colonies, no Moonbase, no exploration of Mars, no interstellar expeditions? Or should we be happy instead with the things we do have: a Solar System far more interesting and odd than anybody had ever imagined, Earthbound telescopes powerful enough to detect planets around other stars, extrasolar planets where nobody would’ve believed planets could exist, an universe fastly more wonderful than any science fiction writer ever imagined?

Me, I’d rather go for wonder than for disappointment; I just wish much of science fiction would do the same and embrace the universe we live in rather than the universe we wished we lived in. Too much modern science fiction wallows in nostalgia or tries to refit the real universe into the old cliches.

Jeffty is five


(I wrote this last year and had always intended to come back to it, but I never did, until Nicholas reviewed Harlan Ellison’s Deathbird Stories and reminded me of this again.)

It was Kip’s post on Harlan Ellison and his trademarked name that reminded me of Ellison’s celebrated short story “Jeffty is Five”, which I had also just reread it again, so it was fresh in memory anyway.

I must’ve read “Jeffty is Five” about a dozen times by now; it’s a well anthologised story, winner of both the Nebula and the Hugo award. The first time I read it, some twenty years ago or so, I quite liked it, but over time I’ve become more and more uncomfortable with it.

As the Wikipedia summary puts it, “Jeffty is Five” “tells the story of a boy who never grows past the age of five physically or mentally. The narrator, Jeffty’s friend from the age of five well into adulthood, discovers that Jeffty’s radio plays serial programs no longer produced on radio stations that no longer exist. They are contemporary, all-new shows, however; not re-runs. He can buy comics such as The Shadow and Doc Savage that are, again, all-new although they are no longer being produced. The narrator is privy to this world because of Jeffty’s trust, while the rest of the world (the world that grew as Jeffty did not) is not.”

In the story, trust and nostalgia are inseperatable. The narrator gains access to Jeffty’s golden childhood world because he has Jeffty’s trust and looses it in the climax of the story by inadvertently betraying this trust. At the start of the story the narrator is out in the cold, untrusting world of seventies America, at the end he’s there again, but made even worse by knowing what he has lost.

As a story, it is a powerful dose of nostalgia, a paean to Ellison’s own lost childhood and the wonders it held, even for people who never experienced this time themselves. There’s always been a stubborn streak of nostalgia in science fiction, an awareness of history to which this story appealed; as its long list of awards shows. It also fits well with the general trend for nostalgia of the late seventies —happy Days, anyone?

Now in general, nostalgia is a reactionary emotion, not just a hankering for an idealised past and a denial of the present, but also a denial of possible future improvement. In small doses this is harmless, but when it controls a discourse, it can be a prelude to authoritarianism. Which is why I’m skeptical of nostalgia these days, especially as seductive as it is presented here. Ellison is quite convincing in his genuine love for nineteenforties pop culture, but unfortunately, this love is stuck in the middle of a quite amoral tale. Let me explain what I mean by that.

First, there’s the treatment of Jeffty’s parents, who are depicted without any sympathy for their plight, as dour, soulles, crushed people with no notion what their son can do, or appreciation of him. Both physically and mentally they’re repulsive. They have to be repulsive and unsympathetic for the story to work, to make the real world that much more dismal, but also because if the narrator felt any real sympathy for them, his joy in sharing Jeffty’s world with him could not be so innocent.

Then there’s Jeffty himself, whose condition is treated as not just positive, but as a wonder, something to envy. Again, this needs to be done to make the story work, but if you think about it, would you want him to stay five forever, or would you want him to grow up?

Finally, there’s the narrator’s treatment of Jeffty, which is nothing short of exploitative. In the heart of the story, when he recounts his time with Jeffty, “the happiest time of my life”, it’s all about him listening to new installments of his old favourite radio shows, seeing his favourite movie stars making new movies of his favourite novels, reading his favourite comics and pulps; you get the picture. It’s all about his pleasure in material things, justified through the lens of sickly nostalgia. (His hatred for contemporary America is also rooted in material matters: rock music, cheap candy bars, junkfood.)

This is why, though I loved this story when I first read it years ago, I’ve found it less and less charming everytime I’ve reread it. It’s well written, but it’s wrong.
