      I am also confused by this. I wonder if he’s underestimating the difficulty of building machine tools and highly precise parts. China with all of its tech level and money to spend still cannot make jet engine turbines, or the highest-end processors. I just don’t see it.

      I think we should have reasonably wide confidence intervals about this because nobody has really tried it, and a few things that we have seen like SpaceX are surprising. SpaceX has a headcount of 7000, Tesla has 45,000. Obviously they rely on the rest of the economy (1/..)

      but we can fudge that by a factor of 10. If you had 500,000 people who were all +2 sigma IQ and conscientiousness, and if they were relatively well organized both politically and economically then it's plausible you would have an "industrial base" that could match the world's.

      You would probably have to not really innovate much and you would be relying on the knowledge that the rest of the world has built up, but it seems reasonable to me, especially moving forward with more robotics and automation (big reduction in number of people needed)

      Again I really want to see an approximate budget & timeline from people who think it’s doable. I don’t have a strong opinion myself but if it’s possible it’s a huge opportunity.

          Why do you think this is an opportunity? I don't think you can do anything profitable with this. Probably the most important application for such ideas is working out how large a self-sustaining colony on Mars/Luna/Antarctica would need to be.

          profit is not the only opportunity...

          but just to be clear I am not claiming that you could make all the products that the global economy makes with 500,000 people. I am saying you could make certain key intermediates like computer chips, steel, power plants etc, and some final products
