Sure, I agree. However, it is also a sign that no new features nor capabilities have been added. > Quicksort is still a useful algorithm after nearly sixty years. Merge sort after almost eighty. I am not sure specific algorithms really compare to a whole suit of algorithms and libraries (i.e., a tool) composing very specific versions of a software like GNU lightning, but sure, both Quicksort and Mergesort are useful since their inception. Try installing Windows 3.1 (don't use VMs please) on your current computer and see if we can really live without updating things.. But I'd argue that if we follow your idea, we can say that the democratic concept is also useful since the 18th century. And still, it has to adapt throughout time and be somehow updated (e.g. allowing women and black people to vote or freely use public spaces like toilets and elevators).
