If for whatever reason uBlock Origin went away tomorrow there would be a fork. uBlock Origin is the second (or third, I forget) fork of the original project.

uBlock Origin is still almost exclusively maintained by the original author: Raymond Hill. He was already behind uBlock and is now working on uBlock Origin (the original uBlock being basically stale).
