The Falcon part of SpaceX is entirely separated from the Starship program, and is run by competent rocket engineers, not by Elon. (I read somewhere that he cannot even set foot there, because it launches military satellites and he does not have security clearance.)
The Starship program is devoted to implementing Elon's paper napkin idea of a rocket -- which is the rocket version of a Cybertruck. Or, better, of the Boring Company tunnels.
