In a way, it did leave subsonic 'offspring', because much of the system archiecture on the 'buses can be traced back to Concorde.
This was certainly true for the analogue A300, and the more I read about the A320 and families (digital), the more it looks as if they inherited most of the same philosophy.
Concorde used the same 'fail passive' and same 'fail operational' and 'standby synchronised hot spare' features.
And of course Concorde was 'fly-by-wire' too, in the literal sense, even if the formal term was "electrical signalling" ("commandes de vol électriques"), and used a stick and yoke, not a side-stick.
Full 'mechanical' back-up (rods and cables) unlike the limited mechanical backup on the digital 'buses.
And the side-stick was first tried on... yes, a Concorde.
