Twitter shares up 4% after billionaire investor Cuban buys shares as AI play

The remarks by Cuban came six days after Twitter reported better-than-expected first-quarter earnings. The social media company has used algorithms to combat user harassment, vowing to prevent abusive behavior and block repeat offenders from the site. Twitter said in its first-quarter earnings release, it "continued to use other machine learning techniques to improve the relevance of notifications, which increased engagement and brought people back to Twitter." In March, Chief Executive Jack Dorsey said the impact of AI on society would be "positive," but he appeared unsure if the U.S. government is ready to deal with the impact. I think so, I hope so.
