In my view, since I was the one that said it, anything more than 5 years away is perpetually 5 years away until it's been proven. Yes, eventually when Starship has enough launches and a track record it will get human rated by NASA to carry astronauts. This is the only actual certification for human space flight worth paying attention to right now. It's possible to get on a rocket otherwise, but the US government isn't going to pay for the ride. Getting flight certified by NASA is expensive and requires a level of experience with the vehicle that doesn't make sense for at least 5 years given we have a cheap and safe ride to LEO via Falcon / Dragon. Nobody is going to rush human flight on Starship, it's only going to have people on it once it's already in space.
