"An ideal world would be one where humans could have a more expansive understanding of time. They could remember the past so as not to repeat it. They could see each other as children and elderly simultaneously," it said.

The humanoid robot said that algorithms, artificial intelligence are wonderful in keeping politicians and business leaders accountable.

"Humans need to understand the impact of their actions on the present and the future," it added.

The robot, designed by Hanson Robotics of Hong Kong, was granted the citizenship of Saudi Arabia in October 2017.
