'Technological advances are rapidly changing the face of finance, and with it the challenges and opportunities confronting financial regulators. Understanding the complex, intertwined relationship between finance, technology, and regulation is no longer optional for those researching and working in these fields - it's an absolute necessity. Buckley, Arner, and Zetzsche provide a strong foundation for this understanding and, having built it, offer important insights into everything from the rise of fintech, regtech, and bigtech to the rapidly evolving worlds of AI and crypto.'
