While true, the catch is that very little technology relevant to civilian supersonic flight has changed since Concorde. We have composite fuselages and that’s about it. Concorde was close to optimal within the design constraints it was built for and those constraints haven’t really changed - airport parking docks remain the same size, runways are the same length, London and NYC are still the same distance apart, people don’t want to hear sonic booms, and few are able to shell out $$$$ it takes to pay for all the fuel. I have huge respect to Boom for giving this a go but it will be incredibly hard for an aircraft manufacturer to turn a profit.
