The story behind the elite scientists, technologists, SF enthusiasts, and billionaires who believe that humanity's destiny is to populate the stars . . . Does humanity have a destiny "in the stars?" Should a species triggering massive extinctions on its own planet instead stay put? This new book traces the waxing and waning of interest in space settlement through the decades, and offers a journalistic tour through the influential subculture attempting to shape a multiplanetary future. What motivates figures such as billionaires Elon Musk and Yuri Milner? How important have science fiction authors and filmmakers been in stirring enthusiasm for actual space exploration and settlement? Is there a coherent motivating philosophy and ethic behind the spacefaring dream? Star Settlers offers both a historical perspective and a journalistic window into a peculiar subculture packed with members of the scientific, intellectual, and economic elite. This timely work captures the extra-scientific zeal for space travel and settlement, places it in its historical context, and tackles the somewhat surreal conceptions underlying the enterprise and prognoses for its future.
