Wise words of Bruce Sterling in "Shaping Things" (MIT Press):
"We need to understand technology with a depth of maturity that mankind has never shown before. We need to stop fussing over mere decade-long "Ages" and realize that there are only three basic kinds of "technology" truly worthy of civilized use. None one them are entirely possible yet.
1. The first kind, and likely the most sensible one, is technology that can eventually rot and go away all by itself. Its materials and processes are biodegradable, so it's an auto-recycling technology. The natural environment can do this kind of work for itself, while also producing complicated forests, grasslands and coral reefs, so, someday, an artificial environment ought to be able to biomimetically mimic that achievement. This doesn't mean merely using available "natural materials" that we repurpose from crops or wilderness. It means room-temperature industrial assembly without toxins. [...]
2. The second kind of technology is monumental. These are artifacts deliberately built to outlast the passage of time. This is very hard to do and much over-estimated. Many objects we consider timeless monuments, such as the Great Pyramid and the Roman Colosseum, are in fact ruins. They no longer serve their original purposes: a royal tomb and a giant urban playground, and they no longer look remotely like the did when their original builders finally dusted off their hands and demanded their pay. Bat at least these "monuments" don't crumble unpredictably, leach into the water table and emit carcinogens while they offgas. [...]
3. The last kind of decent technology is the kind I have tried to haltingly describe here. It's a fully documented, trackable, searchable technology. This whirring, ultra-buzzy technology can keep track of all its moving parts and, when its time inevitably comes, it would have the grace and power to turn itself in at the gates of the junkyard and suffer itself to be mindfully pulled apart. It's a toy box for inventive, meddlesome humankind that can put its own toys neatly and safely away. [...]"
