Links, like any kind of reference, can and will at some point get lost. The same with reference to books, which can disappear, or public records, which can be destroyed by fire, flood, war, mushrooms. The same with your family records, paper, hard drives etc. Even cast in stone, records are bound to crumble into dust at some point.
Life has invented the solution to this issue more than three billion years ago. Individuals are transient, but the code never dies. Just duplicate, duplicate, duplicate. Some copy will survive, and be copied. With errors, but that's life. All-proof concept, as the current crisis shows to those not aware of it before.
I was working yesterday on the records for my ancestor Marie Poulisac (1747-1822). She lost her father at three, her mother at four (found died at the bottom of a well), and just a month after her unique living brother died, eight years old. Orphan with no siblings, in the poor and harsh conditions of her place, time and social extraction (poor farmers in the heart of Brittany), her chances of life were grim. But she grew, married, had children and certainly hundreds if not thousands of descendants today, including one writing here and now about her, over two centuries later.
So, don't be afraid of memory being lost. Copy, copy, copy.
