This film investigates the origins of our love-hate relationship with technology.

Historian Simon Schaffer tells the stories behind some of the most extra-ordinary engineering wonders of the 19th century, including computers made from cogs and gears, giant replica dinosaurs, enormous telescopes, vast steam pumps and devices that herald the birth of cinema.

Through stunning images of amazing machines, the documentary poses questions that still resonate today - will the machines we build save us, replace us or even destroy us?
