Is Twitter's new CEO heading toward a glass cliff?

Less than two months into his $44 billion purchase of Twitter, Elon Musk declared that whoever took over as the company’s CEO “must like pain a lot.” Then he promised he’d step down as soon as he found a replacement “foolish enough” to want the job. That person is Linda Yaccarino, a highly-regarded advertising executive with NBCUniversal. Musk has women in top positions at his other companies, including Gwynne Shotwell, the chief operating officer of SpaceX. But it is also true that women are often more likely to be hired for leadership jobs when there’s a crisis — the so-called “glass cliff.” Could Yaccarino be headed toward it?
