Yeah, I kind of honed in on that one. I've literally been waiting for the smallest mention of regular space travel by a city. Extras was not what I wanted at all.
(Well, it doesn't matter what we do to the Earth, because in a few billion years the Sun will expand into a Red Giant, effectively killing all life on Earth whether or not Humans do anything between now and then. Space travel is literally the only way for anything on Earth to survive that. Personally, I just want to establish a research station on Europa. Not personally, but I want to make the firecracker.)
