Even if microscopic, wormholes that allow information to be transmitted through them would still be interesting if the ends can be moved independently: https://en.m.wikipedia.org/wiki/Wormhole#Time_travel
Sadly that is not how quantum entanglement works.
If it turns out that wormholes are impossible, a future internet powered by neutrinos (presuming we discover/invent a material that can absorb them consistently in a compact way) would be the next best thing.
