metal

Humanity's obsession with this dazzling metal has driven us to violence, exploitation and destruction.

Everything is noisy the metal on metal, constantly keys unlocking doors, gates, and, of course, the prisoners running up and down the stairs all day.

There’s no real reason why a piece of paper or a metal coin should be exchanged for things like shelter or food.

And this is the myth that the brain is a computer that just happens to be made of meat rather than metal.
