              AI is ready to deliver value to your organization, but it's not
              ready to act autonomously. The highest-value applications of AI
              today are assistants, which significantly increase the efficiency
              of workers in operational roles. Software companies are reporting
              30% improvements in developer output across the board, and there's
              no reason AI can't deliver the same kind of value to workers in
              other roles.
