Rapidly Bootstrapping Solar System Wide Civilization

Imagine the possibility that within 50 years, a thousand human civilization equivalents of greater wonder, beauty and prosperity than we have now:

Player-of-Games

Via American Society of Civil Engineers:

Advances in robotics and additive manufacturing have become game‐changing for the prospects of space industry. It has become feasible to bootstrap a self‐sustaining, self‐expanding industry at reasonably low cost. Simple modeling was developed to identify the main parameters of successful bootstrapping. This indicates that bootstrapping can be achieved with as little as 12 metric tons (MT) landed on the Moon during a period of about 20 years. The equipment will be teleoperated and then transitioned to full autonomy so the industry can spread to the asteroid belt and beyond. The strategy begins with a sub‐replicating system and evolves it toward full self‐sustainability (full closure) via an in situ technology spiral. The industry grows exponentially due to the free real estate, energy, and material resources of space. The mass of industrial assets at the end of bootstrapping will be 156 MT with 60 humanoid robots, or as high as 40,000 MT with as many as 100,000 humanoid robots if faster manufacturing is supported by launching a total of 41 MT to the Moon. Within another few decades with no further investment, it can have millions of times the industrial capacity of the United States. Modeling over wide parameter ranges indicates this is reasonable, but further analysis is needed. This industry promises to revolutionize the human condition.

This becomes an ever more tangible possibility as SpaceX revolutionizes commercial spaceflight, and interplanetary propulsion methods reach specific impulses of 250,000 seconds. This is equal to 1 pound of fuel delivering 1 pound of thrust for 250,000 seconds (~3 days), or 250,000 pounds of thrust for one second. Either way it’s a lot! It means rapid (multi-week) flexible travel anywhere in the solar system.
