June - August, 2010


June 4-5. I just finished a famous book that I hadn't read before: The Clan of the Cave Bear by Jean Auel. The idea is, during the last ice age, an orphaned girl from our human subspecies gets adopted by Neanderthals. On one level, it's a wonderful vision of what it might be like to live in a forager-hunter tribe. But on another level, it's not about that at all. We know almost nothing about Neanderthal culture, and Auel chooses to make them patriarchal and authoritarian: women can't even speak to men without bowing down and asking permission first, and the clan has rigid rules which again and again come into conflict with their human instincts. Now, I'm sure this happens sometimes with primitive people, but it's much more typical of civilized people. And when a freethinking young person challenges a dying orthodoxy, we're not seeing eastern Europe in the ice age, but America in the 1960's, or any fundamentalist culture shifting to one that's more free and open. I wonder if the book is popular in Iran right now.

It also reminded me of Harry Potter: an extremely talented orphan joins an exotic community, learns amazing skills, endures terrible hardships, and repeatedly defeats a jealous villain. And last year when I read The Color of Distance, I didn't realize it was Clan of the Cave Bear on another planet.

For a different and equally interesting view of Neanderthals, here's a short article by Stan Gooch on Neanderthals. There's much more in his book Cities of Dreams. Basically he makes a bunch of "two kinds of people" observations, and lines them up so it looks like humans are torn between our Neanderthal and Cro Magnon natures. He also thinks that the big explosion of creativity 35,000 years ago was from the "hybrid vigour" of the crossbreeding. If you think breeding between Neanderthal and Cro Magnon is interesting, wait until we start genetically engineering ourselves.


June 17. Yesterday I saw this reddit comment thread on printers and how they never work right. I live in a house with two printers and I can't get either one to work on either of two operating systems. On my winter tour 18 months ago, everyone I stayed with had a computer, but almost nobody had a working printer. When I want a hardcopy of a google map, I trace it from the screen.

What's going on? I think this is something deeper than incompetence or profiteering, and NiceDay4ASulk is on the right track with the comment that printers are "the bridge between the digital world and the physical world." Maybe this has something to do with entropy: the physical world is like a higher energy state than the virtual world, so it's easy to take a picture of a physical object and put it in a computer, but to go the other way, and turn bits in a computer into a physical object, is extremely difficult.

Some techno-utopians think we're going to have home fabricators, where you can download information and "print" any physical object. But printing text on paper is harder now than it was 20 years ago. As information systems get more complex, and available energy gets lower, we are moving in the opposite direction, copying physical stuff into the digital world, and moving our consciousness there with it.

The problem is that our consciousness is tied to physical bodies that need food and shelter. Where the digital world does not feed us, it starves us, and then starves itself. Or, as I've written before: every sub-world must justify itself in terms of the world that contains it. It would be wonderful if we could use computers to print bacon and glassy metal building blocks, but realistically, if we are using them at all, we will be using them to share information about how to eat cattail roots and build houses out of sand and clay, with our hands.


June 24 - July 8. Was the cowardly lion just masturbating too much? The article's sexual angle is a distraction. The real issue here is that we are using technology to self-administer dopamine, we are getting better and better at it, and it's ruining us. This is what Scott Adams meant when he said that the holodeck will be our last invention. Anne mentions another article in the same magazine with more details on dopamine and addiction.

At the moment, through porn, games, and drugs, anyone in the industrialized world has the option to get dopamine-addicted. But even without these technologies, some people can still do this, if they have strong imaginations. In civilized culture, these are the "dreamers", and a few become great artists and philosophers. In primitive culture, these must be the people who become shamans.

So I'm wondering: now that anyone can get dopamine-addicted, how do you play the advantage of having a strong imagination? Is it better to self-administer dopamine through your own imagination than through external tools? In this society, is it better to get pleasure from solitary daydreaming, than from "useful" activities that are mostly harmful?

A reader argues that you can't get dopamine through daydreaming, and it occurs to me that dopamine is not the only brain pleasure chemical. Which one is it, for example, that you get while you're dozing in the morning? Maybe serotonin? Going back to the original article, suppose there are two people enjoying the same porn, and their brains are responding differently, with one of them addicted to dopamine, and the other one in a much healthier pattern. Certainly there is both healthy sex and sex addiction, so there must also be better and worse ways to have imaginary sex, or to play World of Warcraft, or to read books.

Notice that people who get dopamine-addicted to productive activity are called "workaholics", and it's still not considered healthy! Is dopamine addiction always bad for us? If it is sometimes good, then this might be a helpful rule: it's good to get pleasure from something you do yourself (or as part of a group), and bad to get it from something that is done for you. And if dopamine addiction is always bad, then how should we motivate ourselves?

Maybe we need to exercise more old-fashioned self-control, and it's unrealistic for us to expect to feel good all the time. Here's an edited-down bit from Cory Doctorow's review of the book The Upside of Irrationality:

My favorite is the section on adaptation, the way in which both pain and delights fade down to a baseline normal. Ariely points out that if you take a break, the emotional sensation comes back with nearly full force. We have a tendency to indulge our pleasures without respite, and to take frequent breaks from things that make us miserable. This is exactly backwards. If you want to maximize your pleasure, you should trickle it into your life, with frequent breaks for your adaptive response to diminish. If you want to minimize your pain, you should continue straight through without a break, because every time you stop, your adaptive response resets and you experience the discomfort anew.

I also stumbled on this great blog post, The default brain network and ADD. Basically the default network is what the brain is doing all the time when it's not doing anything else, the background "stream of consciousness". And now I'm wondering: do some default networks function well, while others function badly? Could this explain why some people use alcohol or other drugs to "stop thinking"? I'm even wondering about meditation, which attempts to still the default network. Maybe this is only really valuable if your default network is not working right, and you have to shut it down to repair it.


July 1. This Is Not A Weed is a smart article about urban weeds. The big idea is that "native" and "invasive" don't make any sense in the city, since it's a new kind of habitat where nothing is native.


July 12. The Waterboxx is a new device that can water trees in dry areas by collecting dew. You can order ten of them for $275, but since it's made of plastic, this would be a perfect thing to make with a large RepRap.


July 15. Important 1997 article, Places to Intervene in a System. It argues that the leverage point of industrial civilization, where the smallest action will produce the biggest change, is economic growth... but everyone is pushing in the wrong direction!

This new Bill McKibben interview goes from growth to some visions of the future after economic collapse and climate change.

And Fritjof Capra explores Qualitative Growth, in which the world gets better without the numbers getting higher.


July 17. What drowning really looks like. Drowning people don't splash their arms and scream, even if it would attract attention that would save them. Instead, their nervous system forces them to use their arms and mouth to do nothing but take one more gulp of air. This reminds me of how complex systems fail to prevent collapse: when they get in a state of crisis, they focus all their energy on keeping the whole thing going just a bit longer, while sabotaging their long term survival.


July 17. The perils of rationalization: if you base your decisions on what you are able to explain to other people in words, you will make bad decisions, but if you don't care whether you can explain your decisions, you will make good ones. Oddly, the actual title of the article is "the perils of introspection", which should encompass much, much more than cooking up words to justify your actions. Imagine, if you can, what it would be like to spend hours and hours doing stuff inside your head, without ever using language.


July 29-31. The Economist covers freight trains vs passenger trains. American freight trains are the best in the world, and this is related to the fact that our passenger trains are expensive and slow: Amtrak has to pay to use railways that the freight companies own, and has to go slow to match the speed of freight. The Economist will never mention that corporations were given the rails in the first place in exchange for conditions that they never met. (See Railroads and Clearcuts.) But if we change the rail system to better serve human passengers, it will not work as well for freight.

Right now the fashionable way to make passenger trains "better" is to make them faster. Everybody wants to brag about their bullet train. But I've taken several cross-country Amtrak rides and was totally happy with the speed. Alexa comments:

People who bitch about American trains have either never been on them, or are entirely too hurried in their lives. Rolling across Ohio at five in the morning, standing in a vestibule with an open window, feeling the moist air moving by, watching the fog lift from the farmfields... I always bring things to do on the trip, and I never do them because I spend so much time staring out the window, being impressed and relieved to see how much of the country is still not inhabited.

My complaint is the cost. This article, How Green Is Your Ride, charts the "energetic performance" of different vehicles, and trains are much better than cars or planes. So why are they more expensive? But notice that freight trains are one to two orders of magnitude better than passenger trains. I'm guessing this is because freight can be packed more densely, but the result is that bicycles are still the most efficient way to move people.

My other complaint is that American trains don't go enough places... but they used to! From this page of PDF links to pre-Amtrak system maps, you can see the American passenger rail system shrink, in less than ten years, from almost 90,000 miles to under 20,000 miles, "in the face of massive, government-run aviation and highway programs." Why did the government do this? Because the nation was filthy rich, and citizens wanted the "freedom" of zipping around in their personal vehicles, and also because the corporations that owned the government could profit more from cars than trains.

But cars require massive subsidies in the form of highway construction and repair. As the industrial economy declines, more and more of the pavement will fall apart -- or in well-managed areas, be rolled back to gravel. Unless super-efficient airships are invented, air travel will shrink to serve only the elite. In this climate, the best move for governments is to shift their subsidies back to rails. Otherwise, the next level down is bicycles and horses, which don't really need a government.


August 12. Sharon Astyk writes about livestock breeding. (At first I thought the title, "What are you breeding for?" meant "Why are you having kids?") Her point is that livestock breeding, in this brief age, has been for massive production using massive inputs. For example, after WWI, German villages replaced "unproductive" weed-fed goats with highly productive grain-fed goats, and the result was that rich people had too much milk while poor people had no milk at all. The same kind of thing happened all over, many local breeds were lost, and now we get to make new local breeds. I would phrase it like this: we need to stop breeding for quantity, and start breeding for various qualities.

For example, I'm growing a Court Pendu Plat apple tree, an 1800 year old variety that still fruits when the weather is erratic. Genetic engineering is said to make crops "more productive", but it's actually being used to make crops better adapted to large-scale high-energy industrial farming. Outside of that context, most GMO crops will be less productive than the old varieties, because they'll die! Of course, biotech doesn't have to be used this way. Michael Pollan has spoken in favor of open-source genetic modification, and I agree. It's dangerous, but it can also be used to very rapidly adapt to industrial collapse and climate change, by churning out new plants and animals that fit the new conditions.
