I have a Comp Eng degree from the 90s, been in the industry since then (~25 years), and I have never heard of Paxos. Even the top results from a Google search yields that Paxos is one of: 1. a blockchain company, or 2. a Greek island. More than halfway down the page there is mention of an algorithm of some kind. Probably not a good example of "baseline knowledge" for a software engineer.
I've got masters degree and I don't think anyone even mentioned word "paxos" or "raft" during my 5 years there.
Fortunely internet is a thing and I could read something about this topic.
I know graduates from various public schools and people who heard about paxos (let alone can implement it) are tiny %.
