You are just ignorant. You should read about distributed systems. Google around for Zookeeper and it's zab paper.

Every (recently with raft protocol) multi master distributed system out there interacts with Zookeeper for assigning leader and maintain configuration.

Do you know how the syntax or api calls look like ? They are node path in a tree. You want to store something ? That's a tree path again. You want to listen to some change ? It's tree path again.

As I said, most people are ignorant here and don't do "true" computer science engineering in daily life.

Most devs simply convert business logic into bunch of apis + adhoc implementation.

Did you ever work at a banking firm ? I've read their codebase - they are structured as trees, every damn thing is tree. It's a headache to navigate, code, heck even the objects are literal trees.

As I said, people are ignorant and think world revolves around them.
