What does Musk indicate is the end state benchmark for the Martian settlement's success regarding population?
Answer
Reaching a population size greater than the number of people present when the first ships arrived.
The ultimate measure of success for the Martian effort is framed not just by infrastructure, but by sustained population growth that signifies a true, self-perpetuating branch of humanity. Musk has indicated that the goal is achieved when the population base on Mars surpasses the initial count of the first settlers who made the voyage. This benchmark implies that the colony has moved beyond being dependent on a continuous stream of new arrivals from Earth, achieving viability through natural growth and continuous immigration.
