I don't really understand why you're being so pedantic about language here. What they said make perfect sense. One can hope to achieve a life well-lived. They didn't say anything about admiring it in retrospect.
I don't know if you're trying to make a point about predeterminism or something with your second comment. Perhaps you could clarify.
Aren't life expectancy at birth figures heavily skewed by infant mortality rates. I think this is quite a commonly misunderstood statistic for this reason. So while it's true that in the past a new born baby's chances of becoming a great grandparent were much lower than they would be today, that would mainly be due to the low chances of them ever reaching adulthood and becoming a parent at all, rather than the chances of parents living beyond 47.
Yes, I tend to like this philosophy in database design, of internal sequential ids which are used for joins between tables etc. and an exposed "external reference". But I typically would use a UUID for my external reference rather than a hash of the internal id.
If you're going to do that then you might as well just use UUID, since you effectively reintroduce the negative aspects of that (infinitesimally miniscule chance of collisions, computation involved in the calculation, etc.)
