“The systems are of a sufficient complexity that it is possible to say the algorithm did it,” Christian Sandvig* says. “And it’s actually true — the algorithm is sufficiently complicated, and it’s changing in real time. It’s writing its own rules on the basis of data and input that it does do things and we’re often surprised by them.”

Heroin isn’t new in Cincinnati, but the recent surge in overdoses is being blamed on an even more potent drug called carfentanil. It’s 100 times stronger than fentanyl, a more common synthetic opioid that is itself much stronger than heroin. Carfentanil is used to sedate elephants. It can be dangerous to even touch it without gloves.
