"We cannot create blueprint for future society, but it is good to think about that. It is good to have in mind a goal. It is constructive, it is helpful, it is healthy, to think about what future society might be like, because then it guides you somewhat what you are doing today, but only so long as this discussions about future society don't become obstacles to working towards this future society. Otherwise you can spend discussing this utopian possibility versus that utopian possibility, and in the mean time you are not acting in a way that would bring you closer to that."
