'Even though Alex was a research animal, he was much more than that. This species of parrot generally lives to be 50-60 years old, so Alex was only middle-aged when he died. According to some reports I have read, it is possible that Alex might have succumbed to Aspergillosis, a fungal infection of the lungs that he has battled in the past. However, the cause of death will not be known until after a necropsy has been completed... Alex's veterinarian is returning from vacation to personally conduct this necrospy.'"
Computers are unreliable, but humans are even more unreliable.
Any system which depends on human reliability is unreliable.
