Musk changed his profile picture to a black one, with a black Earth and a dark space inside. I roughly understand what it means: there is no hope for the Earth. I used to long for his Martian city, but now it's nothing at all. With his personality, even if a Martian city is established, it will definitely not be a paradise for freedom and democracy, but rather a colony society that prioritizes efficiency and will suffer from internal competition until death. The speed of technological development is not that important. Anyway, I don't want eternal life. Eternal life means the extinction of humanity. Earthlings, it's better to solve the problems of Earth first. If the problems of Earth cannot be solved, even if they escape from Earth, the people will still be those people, and the result will be the same.
