Case for Before 2030'[Elon Musk] prophesised on X that the mega-rocket will reach the red planet within five years. 'Starship will be on Mars within 5 years,' Musk wrote in reply to a post on the rocket's latest test flight.' (via Mashable - 3.18.24)
Case for Not before 2030'[Musk] believes it'll be within 10 years but he's always wrong by two or three times — how fast self-driving will be; how fast the Cybertruck will be made; how fast we will get to Mars.
