That's true but actor model achieves freedom from data races by forcing ALL messages to be synchronized. This can be useful in some situations but imo isn't a panacea for concurrency issues
I'm assuming you mean implementation-wise. Only cross-core communications need synchronization and since messages are asynchronous you can pay synchronization costs only ones for the whole batch.
