I don’t think business and rich people will use it either. The Concorde worked because you were in a black hole while you crossed the Atlantic, unable to work and unplugged from what was going on. So saving 5 hours was extremely valuable. Now, we have laptops and in-flight wifi, so you don’t miss much on the plane like you used to. Combine that with ultra luxury first class cabins that make the flight extremely comfortable, and saving some time while having to sacrifice all the amenities that come with a good first/business class cabin on a full sized airplane just doesn’t make sense.
Even private planes just don’t feel like they would make sense. Most private jets are used for regional and transcon, and the time savings would be much less significant at those distances. I feel like most wealthy individuals would rather upgrade to a larger, more comfortable, and/or longer-range jet than to sacrifice comfort, size, and range for supersonic. Only the truly ultra-wealthy seem like they might pick up a few, but that is such a vanishingly small market.
