He says human roles will change in the future.

"The only way for humans to stay in the game will be to keep learning throughout their lives, and to reinvent themselves again and again.

"If you try to hold on to some stable identity, some stable job, some stable worldview, you will be left behind, and the world will fly by you."

Harari says he does not want to live in a world of virtual reality created by computer engineers.

"People like virtual realities because they want to have pleasant feelings and exciting experiences," he says.

"But the basic reaction of the mind to pleasant feelings isn't satisfaction－it is craving for more."

That explains why he practices meditation two hours every day to "get in touch with reality".
