Supersonic is more interesting over the Pacific than the Atlantic. An uncomfortable 7-hour flight becoming a less uncomfortable 4-hour flight isn't really news. A miserable 14-hour flight becoming a tolerable 8-hour flight is, both for passengers and possibly even for the burden on staff. IIRC the old Concorde just didn't have the range, but any improvement in the underlying tech could change that.
I think we’ll eventually have some technology to make this realistic.
Supersonic flights powered by jet/rocket engines might not be it for all we know. IMO we are still pretty early in the history of aviation as a technology.
