> Entanglement isn't particularly useful for communication
I would say is false. Entanglement lets you do some fun and theoretically useful stuff for communication tasks. At the most basic level sharing entanglement lets you upgrade a classical communication channels you have into a quantum one (sending 2 bits and burning an entangled pair lets you send a qubit). You can do increasing fancy stuff if you so wish, if you are sufficiently paranoid you might be interested in device independent cryptography, which is only possible because of entanglement.
Yes, they are fun, but not notably useful, at least not yet. And only useful for pretty specialized tasks like key exchange.
