Humanity’s earliest, truly transformative general purpose technologies were the ability to cross-fertilise plants and cross-breed animals. Suddenly, it made more sense to farm than to hunt and gather. The surge in agricultural output meant humans could do other things than worry about survival; they could live in cities. Human civilisation began.
The story of the subsequent millennia has been how some 30 general-purpose technologies of equal power, ranging from the printing press to the steam engine, have driven similar leaps in transforming our economy, our lives and our civilisation. Today, we are living through another.
