The good news is, no one is going to create colonies on Mars. So we can ignore Elon's Star Trek fantasies and appreciate the fact that Space X has reduced launch costs. Shame about polluting the skies with all those satellites that are messing up ground-based astronomy... Elon has a great talent for extracting money from gullible venture capitalists. Sadly, he doesn't have any other talents. But from Mars' perspective, that's a very good thing indeed.
