CRDT is really only useful when inconsistencies could be acceptable in some situations and so it depends on the application.

For something that is trying to solve the general problem of consistent single ground-truth log, you can't really do much better than Spanner.

the "conflict-free" in crdt is like miller high life being the "champagne of beers." it really means conflicts ignored and conflicting items discarded by established rules, which works well for some use cases, but for many does not.
