No comment.

edit: Ok comment. perhaps spacex is not the best comparison though. SpaceX had tremendous necessity driving it. The need for launch vehicles for commercial, scientific, and military purposes.

There is no similar necessity for supersonic commercial aviation.

A Boom customer isn't going to watch 14 test failures and say "well we have no other choice we gotta get people from ny to london in 2 hours" but there was a "we MUST be able to launch people and things into orbit on a US rocket" driving spacex.

Not certain about "tremendous necessity driving" SpaceX. At the time few would have bet that SLS and Starliner would become the duds they are. Maybe Atlas and Ariane incrementing without re-usability and costly Starliner would be viewed positively since there wouldn't be an alternative story (unless BO did better).
