It's not another story, the quality of the reasons for scrapping / upgrading devices is the most important thing here.
If the reasons are "the current devices are insecure or likely to become insecure" that's very different from "the new encryption system is a little bit better so there's not much point in upgrading".
If quantum computing never becomes a practical thing, the current hardware and software will stay secure. If it becomes practical, they won't. Seems simple enough.
