Isn't the whole problem with boom shaping that it requires a thinner fuselage meaning you transport even fewer people? I just don't see this being viable. Musk

Isn't the whole problem with boom shaping that it requires a thinner fuselage meaning you transport even fewer people? I just don't see this being viable. Musk has talked for a long time about a supersonic jet that would fly higher and thus not be heard on the ground. However batteries would need to get quite a bit better still and it would be a massive expansive project.
