Yes, survivorship of the total population of the production run matters when determining the likelihood that any particular item chosen at random survives. So if 50K out of 100k of an item produced 50 years ago are still around and functional, that would tell you something about the products longevity. However, if you just have examples of items that have last 50 years, but aren’t considering or don’t know, how many were initially produced you can’t determine what the probability of survivorship is.

For me the metric this sub should be striving to promote is engineering and materials.
