@ovid it's a pretty hot take for him to call it as successful as SLS in some respects, but I don't disagree with the reasoning: "If SpaceX had stuck an ICPS and the Orion spacecraft hardware on top of Super Heavy, it could have gone to the Moon on Saturday." It seems like they could be operational already if they had a "traditional" barebones 2nd stage instead of going for full reuse. Imagine the possibilities from having a Centaur as a 3rd stage...
