In this issue of BILLIONAIRE themed on the Next Generation, we speak to a quintet of second-, third- and even fifth-generation business scions about how they have managed the succession process and retained the values of their forefathers: Alex Assouline, of the eponymous luxury publishing house; Patricia Gucci, grand-daughter of Guccio Gucci; Charlotte Symington, fifth-generation of a port-growing empire; Marie-Julie Gheysens, 29-year-old scion of the Ghelamco developer; and Arnaud Zannier, an entrepreneur forging a different path to his fashion magnate father Roger Zannier.

We also look at the next generation of industries, including four inventions that could change the world; transformative design in health and waste, whether AI could spell the death knell of creative industries; and how hydrogen-based fuel is getting lift off.

We also explore how the fine-wine world is becoming more diverse, after centuries of being almost exclusively the domain of white, middle-class males.
