OpenAI CEO Sam Altman praised AI startup's President Greg Brockman. "An ideal cofounder looks like…Greg Brockman. OpenAI wouldn't have happened without him," Altman said. "Elon and I were both busy with day jobs, but Greg kept everything moving forward," he added. These remarks come amid the OpenAI lawsuit filed by Elon Musk against Altman and Brockman.
