Brett Scott tells an urgent and revelatory story about how the fusion of big finance and tech requires "cloudmoney" - digital money underpinned by the banking sector - to replace physical cash. He dives beneath the surface of the global financial system to uncover a long-established lobbying infrastructure: an alliance of partners waging a covert war on cash. He explains the technical, political, and cultural differences between our different forms of money, and shows how the cash system has been under attack for decades, as banking and tech companies promote a cashless society under the banner of progress.
