There have been a couple of discussions about doing GPSDOs using only analog
components in the past. People fare more knowledgable than me have commented
there on what the challenges would be and how to solve them. So I recommend
to go through the archives and look for those discussions. They might be a
little bit hidden, though.

the prosperity and technological sophistication in the world is of no
