Boom and others are trying to re-enter the supersonic space with smaller jets.

The main problem with Concorde was that it couldn't fill up seats at the ticket prices being charged, and transatlantic subsonic flights were both more comfortable at the equivalent ticket price, and at the flying time sweet spot of 6-8 hours, which is long enough to just sleep and wake up in the morning.

Had SSTs come of age in the '80s and had a range closer to 6000nm, then they probably would've taken off for transpacific flights. 6000nm from HNL gets you to pretty much all of East Asia, Singapore, and the entirety of North America.
