Mark Whittington asks if that’s what the moon will be in the twenty-first century. He also misspells Gerard O’Neill’s name in the process…

I assume that he means in the energy-production aspect, not the exporting-murderous-nutballs-with-a-misogynistic-fascist-ideology aspect.

Maybe, but we’re a long way from it, both in terms of the cost of getting there, and in developing the technologies to make it happen. I think that it’s a race between using space for energy, and developing radical new technologies on earth that will make that unnecessary, and I don’t have my money on either one right now.
