I'm all for increased public transportation, electric cars, and renewable energy. But I'm also hoping to give people ideas for what would be ideal. I think you could argue that my idea is less fantastical than Musk's. People have built and migrated to new cities since the dawn of civilization. It's a more recent phenomenon that we stopped building large cities. My idea doesn't require any new technology. It doesn't require the government to do that much. It doesn't require people to behave any differently that what is natural.
