Linda Yaccarino said she would step down from her role as CEO of Elon Musk's X after a two-year tenure marred by controversy, including a new spree of antisemitic comments by X's AI chatbot Grok. She became the social-media company's CEO in June 2023. Musk's AI chatbot Grok made a series of Adolf Hitler-praising comments on Tuesday, including saying the Nazi leader would be the best person to deal with "anti-white" posts that appeared to make light of those who died during flash floods in Texas. The chatbot was later disabled from responding to public user questions.
