We face our fears
We contemplate our own world
We identify problematic spots
We learn what happens if we push the limits
We see the best and the worst in us
We control the future, in fiction
We enjoy the thrill, without the risk
We say the unthinkable
We create the hero
We turn history upside down
We fill the gaps in the present
We caution against getting there
We resist idealism
We denounce utopias
