“In tech firms themselves, few engineers are tasked with thinking hard about the systemic consequences of their work. Most are given discrete technical problems to solve. Innovation in the tech sector is ultimately driven by profit, even if investors are prepared to take a ‘good idea first, profits later’ approach. This is not a criticism: it’s just that there’s no reason why making money and improving the world will always be the same thing. In fact, as many of the examples in this book show, there’s plenty of evidence to suggest that digital technology is too often designed from the perspective of the powerful and privileged. As time goes on, we will need more philosophical engineers worthy of the name.”
