Remember when Las Vegas was set to receive the country’s first high speed rail between there and LA until Elon Musk promised the city commission that he could do it cheaper using the hyperloop? And then the hyperloop became a murder subway until it eventually crumbled beneath his hubris?
Getting a rocket (or even a spaceplane) into space and sending a crewed mission to mars are VERY different challenges.
Let alone the colonization claims/promises that have been made over the years.
And… this is exactly what musk has been living off of for over a decade now. Spacex is a company with a LOT of great accomplishments (mostly because it was actually founded by engineers from NASA and JPL who took advantage of a money mark to poach staff from every other aerospace company/org but…). But it is almost exclusively focused around:
Getting satellites/payloads into orbit
Crewed missions to orbital stations
But musk has spun that as he is a god of space and is going to be colonizing mars any day now. Which is a VERY VERY VERY different challenge.
Think of it like this. Someone is REALLY good at driving a speedboat around a local lake. And they keep talking about how they are going to be sailing across the Atlantic Ocean any day now.
