Supersonic passenger aircraft were operated profitably and no longer exist.
There’s levels of R&D required for many technologies where the question goes beyond could this be profitable to what are the risk vs reward that this specific project will succeed.
Were they? Did Concorde provide return on investment? When was the break-even expected? Sure, if we look at it as R&D subsidized by governments of UK and France, then yet, it was profitable.
In particular, the problem with it was that it could not get to supersonic speeds over urban areas, which significantly limited routes where it made sense, and the range was not good enough to cover longer distances.

Were they? IIRC joint project by British and French national airlines, they expected to sell loads, hardly anyone wanted to buy the planes, the two airlines kept them flying out of government embarassment.
But after accounting for maintenance & etc were they more profitable than sinking the equivalent amount of money into something else, such as slower aircraft? Notably there are currently efforts to develop new supersonic passenger liners.
