Re: Jealous much?
I think you're confusing a couple of things. The crew dragon which will fly humans to the ISS - is completed. They had to replace some valves after the super draco explosion but it's essentially completed and very much realistic not SF because it's already been to the ISS and back just without crew.
However, success with the crew dragon will not sink SLS because they're different systems designed to do different things. Success with the Starship is what could sink SLS as a fully functional SS + SH stack will make SLS redundant.
Finally, why do you think Elon is delaying things?
