> CRDT picks 2

They don’t have to.

The crdt library knows that value is in conflict, and it decides what to do about it. Most CRDTs are built for realtime collab editing, where picking an answer is an acceptable choice. But the crdt can instead add conflict marks and make the user decide.

Conflicts are harder for a crdt library to deal with - because you need to keep merging and growing a conflict range. And do that in a way that converges no matter the order of operations you visit. But it’s a very tractable problem - someone’s just gotta figure out the semantics of conflicts in a consistent way and code it up. And put a decent UI on top.
