bootstrapping itself by extending tech designed decades ago? that doesn't sound right. Until today, the biggest rocket design was still the soviet N1 from the 60s. It's good to celebrate space achievement but rewriting history is annoying
Wiki:
N1 LEO payload is ~95 t, weight 2750 t, height 105.3m
Starship LEO payload is 100~150 t, weight 5000 t, height 120m.
