Linda Yaccarino may be “exactly what Twitter needs.” But is the new CEO being set up to fail?

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, Musk announced Friday, is Linda Yaccarino, a highly-regarded advertising executive from NBCUniversal. She’ll start in six weeks. How long she’ll last might depend on her pain tolerance.
