Yep. The routes look like flights of fantasy rather than reality. A stopover in the Soviet Union? Flights crossing large parts of a US that had banned supersonic flight? Regular all business class flights between Lisbon and Caracas? [the actually-built generation of Concordes can and did fly Paris/Caracas with a stopover in Lisbon... just not very frequently]
The improvements to fuel economy, range and sound would have made little difference to the commercial viability of a niche of aircraft that already spent most of the time on the tarmac because the tiny handful built and basically given away weren't allowed to fly most routes or remotely approach economic viability for most others.
The governments threw their money at a project later called the Airbus A320 instead. Difficult to say they were wrong...
