@jirislavicek9954 Yes, I meant that Elon will keep dreaming about colonizing Mars, building self-sustainable city, making the life multiplanetary and so on, while American administration slowly losing their minds and the World comes closer to WWW3. America can NOT achieve those global goals alone, without Russia, China, and many other countries, but meanwhile, the US is heading in the opposite direction, bringing the World to the edge. So, Musk can keep on dreaming...

@jirislavicek9954 This is the level of Musk's "sceintific" approach to building city on Mars. He thinks that a million tons of cargo is enough to make fully self sustainable city on Mars. Really??? City that would be fully independent from Earth?
Let's say, the city will have 1000 citizens. So, it's 1000 tons for each person. Does it sound much? Yes, but only for people here, where we have everything already. On Mars, there is no water, no air, no food, no houses, no furniture, nothing.
First, let's just calculate how much air and water one person consumes every day. Then, the food. Then, fuel for generating electricity for heat, light, machinary (sun energy is obv not enough), vehicles, robots ect... But it nothing compared to the weight of steel, glass and concrete needed for constraction of giant dome and spaceport for arriving starships. And whose gonna build anyway? Exhausted and sick people in deadly radioactive desert with 37% of earth gravity? What for? Resources? No much resources on Mars. Reaserch? The probes and robots can do it. For tourism? Ha-ha. No, only for Musk's ambitions, while he stays here and inspire feefteen years old...
If we want to do it right, we need:
1. Develop new type of rocket engine that will provide 10 times greater speed, so we can get to Mars much faster than 6 months.
2. Solve Space and Mars radiation problem, so we get to the destination and stay there as healthy as we have been on Earth.
3. Engineer constraction robots with next generation AI, and send them to Mars firts, alongside with materials, so they will build all human life support infrastructure from scratch and make it ready for us.
4. Develop terraforming technologies, build an equipment, send there and start process before people start populate red planet.
5. Solve the gravity issue in space and on Mars.
If we do it Musk's way many, many people will die. It is very stupid to send people on 6 months jorney exposed to sun gamma rays and then poison dust of Mars desert, to build extremely complex structures in a third of Earth's gravity and huge day/night difference in temperatures while they are physically sick and emotionally exhausted. That's not just hard, it's impossible.
