Whatever Happened to the World of Tomorrow by Brian Fies is a paean to the worlds of the future that were envisioned in the early to mid 1900s. The book covers the 1939 World’s Fair through the end of the US Space Missions in the mid 1970s to show how the future that was always destined to come has never arrived. It also is a story of the relationship between a boy and his father and how it changes as the world changes. It is an evocative look at technology’s relationship with people as the world moved on.
