Re: "Even if it's basically a fifty years old design"
Um, sorry, but the wheel is a thousands-of-years-old design, where's the problem ?
If it was a 50-year-old rocket, yeah, I could see the issue.
Designs do not grow old, they get replaced by better designs.
SpaceX et al are apparently in the process of doing that, but the Russkies have a design that works now. They might just have to tweak it, but with its track record, I'm not sure that's a very good idea.
