The Tin Woodman knew very well he had no heart, and therefore he took great care never to be cruel or unkind to anything… ‘When Oz gives me a heart of course I needn't mind so much’.

• L. Frank Baum

We love the story of the Tin Woodman because it represented a divergence of ideas, in contrast to the dystopian story that gave us the word, “robot”. In L. Frank Baum’s world building, humanity could be found in the strangest of places, and automation had the burden of an even stricter ethical standard.
