We will not have supersonic transport for average people unless outsiders do it first. There are only two meaningfully large manufacturers now, Airbus and Boeing.
Boeing and Airbus both cannot financially afford a technologically promising but possible failure now. Boeing built the 737 MAXX because they couldn’t afford a clean sheet update of 70-year old technology despite the savings. Airbus lost almost as much as the entire company was worth on the A380, kept afloat by EU subsidies.
