There is little benefit to supersonic, most time spent traveling to far off places is wasted on time zone adaptation/jet lag, and it's nicer to do that in a slower plane with a roomier business class seat you can sleep in. They're solving a problem nobody has. Further, these planes pollute massively, much more so than regular flying, and the planet can't take that anymore. Wave that away with biofuels, but that just makes flying multiple times more expensive on top of the existing supersonic cost multiplier. Also, the sonic boom annoys the shit out of people trying to sleep on the ground. Sunset industry.
