Wishful thinking, delusion or scam.

There are so many foundational issues with low supersonic flight from a usability perspective as well (time zones are not your friend for some of it), that lots of routes can only command a premium in one direction.

You have to make so many rosy assumptions to even believe this makes sense if someone was willing to pour billions into engine tech - and still maybe have no options that are commercially viable. It’s also a nightmare from an environmental perspective.
