Boom is basically a scaled down Concorde when you look at it from a distance. They've reduced the speed somewhat to keep the fuel burn within certain limits, but it has the same drawbacks that Concorde had: a supersonic boom and enormous fuel burn per passenger. In this day an age of Climate Hysteria this simply won't fly. I foresee the failure of all supersonic airplane ventures until NASA comes up with a viable sonic-boom free design. Even then, the fuel burn could still make it unsalable.
