Spacex first landed an orbital booster just over 10 years ago and have now landed 600 times.
The entire rest of the world combined has done it twice.
For a long time people would scoff when it was said they had a 10 year lead, and that others would catch up quickly. Proof meets pudding.
FTA: "SpaceX suffered upper stage failures on three test flights of the massive Starship rocket last year. "
SpaceX has also had numerous failures with the larger generation of second stages and currently doesn't have a lead there. Nobody does.
