Earlier quoted context omitted.
“ Space is orders of magnitude more complex than air flight” Not true! The challenges are different but space is in a sense simpler since the reliability requirements for space are not as stringent.
That's an odd assertion. Sure, we have a somewhat higher tolerance for risk for unmanned spaceflights, but we don't have particularly high requirements for unmanned drones either. But the reliability requirements for something like Starliner are ridiculously high and that's why it's taken a decade for the first manned flight.
“An airliner has to survive 13 hours in the air. A rocket only has to survive 13 minutes.”
