Robotics for conquest of space

I don't think robots are quite there yet. If they were,
you'd see such set-ups on Earth. But robots can certainly
be multipliers. You can build a Moon base with twenty
people and a bunch of robots, and get more work done than
five hundred people without the robots.*

I like robots, really I do, but I don't think they're quite
there yet. And since I want lots of PEOPLE in Space, that's
A-OK with me.

* 20 and 500 are guesses; if it's actually 15 and 1,000 or
50 and 500, well whatever. Let's just get the machinery and
however many people it takes and start already!
