Photojournalist Natalie Behring visited Guiyu, China and documented the world's biggest digital dump where, for $2 per day, the locals sort, disassemble, and pulverize hundreds of tons of e-waste. The payoff is huge: computer waste contains 17 times more gold than gold ore, 40 times more copper than copper ore. But the detritus also leaches chemicals and metals into local water supplies."
Computers are unreliable, but humans are even more unreliable.
Any system which depends on human reliability is unreliable.
