From Technology Review: Interesting… I would have picked a couple of these (like cosmetic implants and landmines), but some I never thought of the car as a technology that should go away. But their arguments for finding good replacements make sense.
1. Nuclear Weapons, 2. Coal-Based Power, 3. The Internal-Combustion Engine (yeah, the car), 4. Incandescent Light Bulbs, 5. Land Mines, 6. Manned Spaceflight, 7. Prisons, 8. Cosmetic Implants, 9. Lie Detectors, 10. DVDs.
