The future’s alright

futureThe role of science fiction vis a vis the future and predictions thereof has always been a target of lighthearted mockery. However Centauri Dreams articulates, with the help of futurist Peter Garretson, what science fiction can offer, even if predictions aren’t always on the mark:

Many forays into fictional futures, then, can give us alternative ways to make a new concept real. We can try on those futures by reading stories that make them come alive, seeing what effects these changes would have on society. And we can do more. By placing futuristic concepts in a tangible, fictional context, we can encourage their growth and dissemination.

Science fiction explores how human beings respond to change and disruption, and as such helps us explore ourselves. It can also offer pictures of how the world could be, so as to encourage us to actualise these images and build a better future.

The next 100 years

Pivot_areaGeorge Friedman, writing in The New Statesman magazine, has an article up on the next 100 years, as seen through the theoretical prism of geopolitics. This is a doctrine that emphasises the importance of the permanently operating factors of geography in determining global dominance:

Thus, the question is how these geopolitical and strategic realities shape the rest of the century. Eurasia, broadly understood, is being hollowed out. China is far weaker than it appears and is threatened with internal instability. The Europeans are divided by old national patterns that prevent them from moving in a uniform direction. Russia is using the window of opportunity presented by the US absorption in disrupting the Islamic world to reclaim its sphere of influence in the former Soviet Union, but its underlying weakness will reassert itself over the next generation.

New powers will emerge. In the 19th century, Germany, Italy and Japan began to emerge as great powers, while in the 20th century global powers such as Britain and France declined to secondary status. Each century, a new constellation of powers forms that might strike observers at the beginning of the century as unthinkable. Let us therefore think about the unthinkable.

Friedman paints a rather pessimistic picture of a future of exactly the same kind of nationalistic war that took up most of the 20th century.

I’ve never been comfortable with tub-thumping nationalism/patriotism as something to dictate beliefs and action. To me the future of the people living on Earth is as much about cultures, attitudes, and society as it is about the fight for power between specific nation states [1].

But states will remain the single most powerful entity on Earth over the next few decades, and as such it is worth thinking about which of them might gain greater influence in the future.

The central conclusion of Friedman’s article is that “they that control the North American continent, control the world” as they will have access to both the Atlantic and the Pacific Oceans as well as the vast wealth of the North American continent. As such he posits Mexico as a potential rival to US power. He also suggests that Japan might engage on further military ventures. Turkey may become the core of an Islamic sphere of influence in the Mediterranean and Middle East.

[1]: Inasmuch as particular states have particular cultures and attitudes (e.g. pluralism, rule of law, liberalism, democracy, individual freedom) I think that it is a mistake to support a nation state because of the attitudes it purports to value, rather than the reality of its actions. You support the people and the ideals first, the countries second.

Swarming to it

iswarm4One of my favourite[1] plausible science fictional tropes is that of tiny robotic insects. The latest step towards their instantiation has been taken by researchers in Sweden, Spain, Germany, Italy, and Switzerland as they put forward their conception of how swarms of mass-produced robotic fleas could be used for surveillance, cleaning, and medical applications:

The technique involves integrating an entire robot – with communication, locomotion, energy storage, and electronics – in different modules on a single circuit board.

In the past, the single-chip robot concept has presented significant limitations in design and manufacturing. However, instead of using solder to mount electrical components on a printed circuit board as in the conventional method, the researchers use conductive adhesive to attach the components to a double-sided flexible printed circuit board using surface mount technology.

The circuit board is then folded to create a three-dimensional robot.

I can imagine that once this sort of technology matures it will herald a profound change for society. An Orwellian Panopticon where everyone and everything is traced and followed and tracked will become a practicable possibility. Privacy will become one of the most valuable commodities on the planet, with the richest and most powerful people cowering in enclaves sterilized against micro-invaders.

[1]: In that I enjoy them as part of a story and am not entirely ambivalent to their actuality.

Speaking of marine conservation…

garbage_in_ocean…as we were, here is news of the first incursion into the collossal garbage patch that has collected in the Pacific Ocean:

Scientists surveyed plastic distribution and abundance, taking samples for analysis in the lab and assessing the impacts of debris on marine life.

Before this research, little was known about the size of the “garbage patch” and the threats it poses to marine life and the gyre’s biological environment.

On August 11th, the researchers encountered a large net entwined with plastic and various marine organisms; they also recovered several plastic bottles covered with ocean animals, including large barnacles.

“Finding so much plastic there was shocking,” said Goldstein. “How could there be this much plastic floating in a random patch of ocean–a thousand miles from land?”

This reminds me of the great junk armada depicted in Snow Crash by Neal Stephenson.

Intelligent design vs. natural selection

flowerEric Drexler has written a paper entitled Biological and Nanomechanical Systems: Contrasts in Evolutionary Capacity that explores the differences between biological organisms and artificial machines, specifically why some products of intelligent design (i.e. design by humans) could never be created by natural selection. Drexler has written a short preface summarising his argument here:

The basic argument is as follows:

  • Evolvable systems must be able, with some regularity, to tolerate (and occasionally benefit from) significant, incremental uncoordinated structural changes.This is a stringent contraint because, in an evolutionary context, “tolerate” means that they must function — and remain competitive — after each such change.
  • Biological systems must satify this condition, and how they do so has pervasive and sometimes surprising consequences for how they are organized and how they develop.
  • Designed systems need not (and generally do not) satify this condition, and this permits them to change more freely (evolving in a non-biological sense), through design. In a design process, structural changes can be widespread and coordinated, and intermediate designs can be fertile as concepts, even if they do not work well as physical systems.

As I read it (and I could be wrong) the basic notion underlying Drexler’s argument is that the kind of mechanical precision demanded by human engineers is not present in the products of natural evolution. Artificial technologies are not yet fungible. If you remove any part of your CPU it will not work. If you remove some parts of someone’s brain then it still works. If you make a small alteration to an organism’s genome it may still work.

In order for evolution to work the replicator needs to function even when it has some small mutation. Artificial technologies generally don’t work when there is some small error in the manufacturing process.
