Utter nonsense.
Look, we all acknowledge the accomplishments Mother Russia, OK?
But stop trying to make out that this is either high tech or difficult to make. Its a very basic simple design (as is almost all Russian space hardware), simply scaled up.
Engines with the exact same principal of operation powered the Shuttle. It had the additional requirement of being reusable. SpaceX already has the Raptor engine in production and testing.
The metallurgy is not a particular impediment, because it was already developed for prior rocket motors (F1) as far back as the 50s.
