Even the 100+ year phone system is a dying approach. Ignore the technology
evolutions that have and are still occurring under the covers, the whole
concept of a string of nonsensical digits as an identifier is being replaced
with alpha strings that people already associate with the target. The idea
that any modern technology will persist unaltered for more than a few
generations is something worth considering but at the same time poses
baseless hubris on those that attempt it.
