I think to a lay public it is helpful to clarify that, even in such long range examples of entanglement, the things being entangled still tend to be small!

In principle there is no reason why an arbitrarily large object cannot be put in an entangled state. But as a practical matter the effects of interaction with the environment (so-called "decoherence") seriously limit our ability to construct such systems in real life.
