According to Wiki

Falcon 9 was announced in 2005

First launch in 2010

By the third flight they were delivering to the ISS

Starship .. it's a bit unclear when they started designing it b/c they kept changing the design. But It's been in design for ~10 years.

> As of August 26, 2025, Starship has launched 10 times, with 5 successful flights and 5 failures.

10 launches.. and not even in orbit. Not to speak of ISS. I'm sure they'll make it work eventually, but I would expect with experience the design time would decrease, not increase. Starting from zero, making the first rocket engine has got to be much much harder than making an improved iteration (even if more complex)
