> "spooky action at a distance" connected devices We have that; it's called radio. If you're hoping for something spookier and more quantum-mechanical, then see e.g. https://en.wikipedia.org/wiki/No-communication_theorem https://en.wikipedia.org/wiki/No-communication_theorem which implies that under quantum mechanics as currently understood, entanglement cannot be used for communication.
