I'll offer up that I've had a hard time wrapping my mind around them and that in practice it seems like you need to implement a check pointing operation on top of them which is necessarily not conflict-free, or your replication log will expand without bound & eventually overwhelm your system. (Though perhaps not, depending on your problem domain. Not CRDTs but in this interview the engineers discuss a massive, high frequency replication log that they don't checkpoint, which they've been running at scale for years. Though you could also say they implicitly checkpoint every trading day, and they're working on implementing checkpointing. https://signalsandthreads.com/state-machine-replication-and-...)

That being said I would use CRDTs for any greenfield collaboration project.
