@sciss I wrote a "Detritus Manifesto"¹ like 12 years ago along these lines. If you want something more recent and rigorous @manetta pointed me to the "Minimal Computing"² movement. (she may have more slow computing ideas). I've always been a fan of "rustic computing" so if you want to collaborate on a little polemic, just say the word.
