Elon Musk claims that building a city on the Moon could be achievable in less than 10 years?

SpaceX's strategic shift: the Moon may come before Mars, pointing the first step of deep space settlement toward the Moon.
Compared to Mars, which requires waiting for a 26-month window and a 6-month journey, the Moon allows for launches every 10 days and direct trips in 2 days, enabling rapid testing and iteration of city construction. Prioritizing the future of human civilization, the Moon is seen as a faster landing option.
The Mars program will still proceed, but the true interstellar city might start on the Moon first.
