SAN FRANCISCO (AP) — Elon Musk says he plays on remaining as Twitter’s CEO until he can find someone willing to replace him in the job. Musk’s announcement came after millions of Twitter users asked him to step down in an unscientific poll the billionaire himself created and promised to abide by. Since taking over San Francisco-based Twitter in late October, Musk’s run as Twitter CEO has been marked by quickly issued rules and policies that have often been withdrawn or changed soon after being made public. He has also alienated some investors in his electric vehicle company Tesla who are concerned Twitter is taking too much of his attention.
