In 1998, a pharmaceutical company suddenly lost the ability to make their lifesaving HIV drug at one of its production facilities. Then that failure spread to the company’s analysis labs. Then it spread to the other production facility, and within months the lifesaving drug had effectively vanished from the entire planet. And this wasn’t the first time something like this had happened. How does a chemical just… disappear?
