Want to reduce the time it takes to get somewhere? Reduce the security circus at airports. This will cut off way more of the travel time for the majority of flights, wothout the downsides of supersonic planes.
You're going to have some security in any case and have since at least the 1970s. And it typically takes me <10 minutes even if I allow some extra time for the potential that it could be longer if it rarely is with pre-check.
