SpaceX has had 165 launches in 2025 (although admittedly 75% of those were for Starlink...) Obviously bigger isn't more economical or sensical, and most cases are served just fine with the Falcons, but there are cases we need the big boy for, and it's good that someone is working on it and has made so much progress.

Obviously a semblance of a schedule is good to have, but realistically, that's not really how research works. Look at James Webb telescope, it was originally scheduled for 2007, and ended up launching 14 years later. It's still an amazing piece of engineer/science, and it's amazing that it's up there now, even if it was very late to it. It's much better to be late and successful than early and failing.
