Behind every utopian promise of emerging technologies lies a messy reality of physical constraints, legal hurdles, and economic bottlenecks that determine whether an innovation can move beyond the lab.
While engineering can rapidly advance fields like asteroid mining, unclear legal frameworks and daunting operational costs can keep promising ideas from becoming viable industries.
Grand technological visions frequently stall because they depend on single, unpredictable material breakthroughs, such as the elusive carbon nanotubes required to build a functional space elevator.
Many of the book's most exciting technologies run into the same bottlenecks: physical limits, extreme expense, biological complexity, and difficulty moving from prototype to widespread use.
