Peaking obsolescence in turboprops and early jets

Late turboprop aircraft and early jets illustrate how the best mature design can be approaching obsolescence even while it outperforms the first generation of a successor technology.

Question

Does being more technologically advanced always keep a system useful for longer?

Short answer

No. A mature technology can outperform its early replacement while still having less long-term development potential.

Notes

Peaking obsolescence describes a mature technology that remains highly capable even as a newer line overtakes its future potential. Postwar turboprop aircraft could be more useful than contemporary early jets because piston-and-propeller development was mature while jet technology was still young. The turboprops had less room for further improvement, whereas jets would eventually reach performance levels the older line could not match. Immediate performance and long-term development potential therefore need separate judgments.
