Concorde wasn't transformational for business at a time when executives couldn't work and videoconference from anywhere in the world and stay connected to the workplace for the majority of their flight duration.
The realistic potential of an operationally-expensive medium range aircraft designed for scheduled passenger flights isn't going to radically change trucks, trains and Zoom. Or business jets, for people that care enough about time to pay for it in thousand dollar multiples. Even for the small fraction who can actually afford it, a supersonic airliner is still going to have range constraints eliminating the possibility of quickly crossing the world, and for the transatlantic hops it might manage, it's the 8am JFK-LHR flight competing with a business jet at a time and origin/destination airports of the executives' choosing...
(for related reasons, I'd actually be more bullish about the economic case for supersonic bizjets, but there have been quite a lot of projects studying that market that haven't got anywhere...)
The supersonic biz jet fails because they all need longer runways. The biz jet wants to land at smaller private airports to avoid the hassle (security) of large airports. Any supersonic biz jet capable of also landing on a short runway ends up looking more like a fighter jet with some extra seats.
The Concorde wound up spending a lot of time at sub-sonic speeds, but really I think if we look to the future of air travel we can imagine surpassing supersonic speeds as well. There are already companies working on hypersonic (Mach 5+) designs with an eye towards consumer applications; obviously rich consumers to start, but that's how it often goes.
Those are some truly societally transformative speeds. You can go from the west coast of the US to Paris in less than 2 hours.
But we can't get to that without iterative improvement.
