Most of Concorde's engineering innovations were tech tree dead ends though. The Concorde project was certainly good at fostering Anglo French cooperation in aerospace but it's difficult to imagine the counterfactual scenario where the cooperation is doomed to failure because the debut product is a commercially viable subsonic aircraft rather than a technically impressive aircraft that doesn't sell. Similarly, whilst some of the R&D investment in control systems did find it's way into the A300, the A320's digital fly by wire is a completely different system, and it's difficult to imagine the scenario where a nascent Airbus project doesn't consider fly by wire because they hadn't figured out delta wings or droop noses yet
