We don't have teleporated robots of this sort, not to mention the
speed of light delay problem. But if we did an they were there, what
are you going to *do* with them? You can't just say ":mine the moon,"
the moon is effectively dirt. What chemical processes are you going
to use? What is power budget? How are you going to make parts?
I have seen a proposal to mine the moon to make silicon solar cells.
It was by real process engineers. Took 20 years and 2 trillion
dollars. I don't recall if it involved any people on the moon.
