Pickens writes "Hundreds of retired New York City subway cars are being sunk sixteen nautical miles off Delaware's Indian River Inlet and about 80 feet underwater, continuing the transformation of a barren stretch of ocean floor into a bountiful oasis, carpeted in sea grasses, walled thick with blue mussels and sponges, and teeming with black sea bass and tautog. 'They're basically luxury condominiums for fish,' says Jeff Tinsman, artificial reef program manager for the Delaware Department of Natural Resources and Environmental Control. Subway cars are roomy enough to invite certain fish, too heavy to shift easily in storms, and durable enough to avoid throwing off debris for decades. Tinsman particularly favors the newer subway cars with stainless steel on the outside to create reefs. 'We call these the DeLoreans of the deep,' he said. But success comes at a price because other states, seeing Delaware's successes, have started competing for the subway cars, which New York City provides free. 'The secret is out, I guess,' said Michael G. Zacchea, the MTA official in charge of getting rid of New York City's old subway cars."
Computers are unreliable, but humans are even more unreliable.
Any system which depends on human reliability is unreliable.
