We're not going to change human nature any time soon. It isn't that we aren't rational -- we are rational -- but reason has limits.
Science and technology, including the social ramifications thereof and lots of sundries.
Or at least he thinks he is:
.... It is at least a possibility to be seriously considered, that China could become rich by burning coal, while the United States could become environmentally virtuous by accumulating topsoil, with transport of carbon from mine in China to soil in America provided free of charge by the atmosphere, and the inventory of carbon in the atmosphere remaining constant. We should take such possibilities into account when we listen to predictions about climate change and fossil fuels. If biotechnology takes over the planet in the next fifty years, as computer technology has taken it over in the last fifty years, the rules of the climate game will be radically changed.
When I listen to the public debates about climate change, I am impressed by the enormous gaps in our knowledge, the sparseness of our observations and the superficiality of our theories. Many of the basic processes of planetary ecology are poorly understood. They must be better understood before we can reach an accurate diagnosis of the present condition of our planet. When we are trying to take care of a planet, just as when we are taking care of a human patient, diseases must be diagnosed before they can be cured. We need to observe and measure what is going on in the biosphere, rather than relying on computer models.
Such vision! Who knew it was that simple: China burns the coal, we sequester their windblown carbon as topsoil. Mirabile dictu! Dyson ex machina.
And who knew that Dyson had such a complete grasp of the processes of planetary ecology. He must, since he feels so ready to propose that we replace all of the current thinking by climate scientists and ecologists with a suggestion by a physicist that we just give up on climate modeling and replace it with a wholistic, diagnostician model.
It's convenient to be so brilliant that one doesn't feel the need to apply the same criteria to his own theories as he does to others.
I've been doing a lot of video blogging on BEYOND THE BEYOND lately, which must be annoying to readers who don't have broadband. But look: outside the crass duopoly of the USA's pitifully inadequate broadband, digital video is gushing right through the cracks. There's just no getting away from it. There is so much broadband, so cheap and so widespread, that the video pirates are going out of business. I used to walk around Belgrade and there wasn't a street-corner where some guy wasn't hawking pirated plastic disks. Those crooks and hucksters are going away, their customers are all on YouTube or LimeWire...
Broadband isn't the problem. Bruce makes his living being a visionary. I make my living doing work for other people. It's truly not the visionaries who actually change things -- it's the people who buy (into) their visions, and those people just don't have the time to look and listen at the same time to continuous "bites" of see-hear content.
Podcasts are bad enough -- I have to listen for as long as someone speaks in order to get their point, I can't really skim ahead or scan around with my eyes. I've got to buy into their narrative construction. And I'm paying for that purchase with my time and attention.
This also goes to Cory Doctorow's point about text bites. He's grazing around, taking in small chunks of text at a go, and the web is fine for that, that's his message. Great. Fine. But text can be time- and space-shifted far more effectively than audio, which in turn can be time-/space-shifted far more effectively than video.
What's really needful as I've noted before is a way to mode shift text into audio without human intervention. Or video, for that matter, if you want to get visionary about it. But I'm not going to worry about video right now, because audio is something that some basement hacker could actually pull off with an evening's work, and refine with the labor of just a few weeks. Or so it seems to me. On my Mac, right now, I can select text and have the machine speak it to me, complete with sentence and paragraph pauses. The Speech service is AppleScript-able, so (if I actually knew AppleScript) I could script it to pick up blog posts and pump them into audio files, that in turn could be pumped onto my audio player for listening in the gym or on the road. If I spent that much time in the gym or on the road. Which I don't.
