What Digital Does to Our Brains

“It turns out that digital devices and software are finely tuned to train us to pay attention to them, no matter what else we should be doing. The mechanism, borne out by recent neuroscience studies, is something like this:

  • New information creates a rush of dopamine to the brain, a neurotransmitter that makes you feel good.
  • The promise of new information compels your brain to seek out that dopamine rush.

With fMRIs, you can see the brain’s pleasure centres light up with activity when new emails arrive.

So, every new email you get gives you a little flood of dopamine. Every little flood of dopamine reinforces your brain’s memory that checking email gives a flood of dopamine. And our brains are programmed to seek out things that will give us little floods of dopamine. Further, these patterns of behaviour start creating neural pathways, so that they become unconscious habits: Work on something important, brain itch, check email, dopamine, refresh, dopamine, check Twitter, dopamine, back to work. Over and over, and each time the habit becomes more ingrained in the actual structures of our brains.”

The Merits of Obsolete Technology

For the old phones actually do what phones used to do, which is to make and receive phone calls, without depositing your whole life in cyberspace where it can be stolen and used to embarrass you before the entire world. According to the New York Times, one of the main attractions of the retro-phone for celebrities is that it helps keep their secrets safe. And, as rocker Iggy Pop says, “You can drop it and it doesn’t break.”

“Even typewriters are bouncing back. Spooked by the WikiLeaks and Edward Snowden affairs, intelligence agencies and political groups are reportedly returning to Cold War technology to keep their secrets safe. The glamour is back, too. Movie star Tom Hanks recently published a “love letter” to the typewriter, declaring: “The tactile pleasure of typing is incomparable… there is a sheer physical pleasure to typing.” Dr Mike Evans, a theoretical physicist at York University, believes that the appeal of high-technology is being undone by its constant quest for what he calls “sterile perfection”…”

Games on Disc More Energy Efficient than Downloads

“This research investigates the carbon footprint of the lifecycle of console games, using the example of PlayStation 3 distribution in the UK. We estimate total carbon equivalent emissions for an average 8.8-gigabyte game based on data for 2010. Two delivery scenarios are compared: the first examines Blu-ray discs delivered by retail stores, and the second, games files downloaded over broadband internet.”

“Contrary to current consensus that downloaded data will result in lower carbon emissions than distribution by disc, producing and distributing an average-sized game by Blu-ray disc in 2010 resulted in approximately 50 to 90% less emissions than downloading. The estimated carbon emissions from downloading only fall below that of Blu-ray discs for games smaller than 1.3 gigabyte. The study findings serve to illustrate why it is not always true that digital distribution of media will have lower carbon emissions than distribution by physical means when file sizes are large.”
