Misleading headline. No one is thinking seriously about building a neutrino network. As the article mentions at the end, the detector has to be massive and the transmitter uses a great deal of power.

There would need to be an extraordinary breakthrough in our ability to detect neutrinos before something like this would be practical.

Neat trick and impressive that they could make it work at all, though.

Or the communications requirements of Earth's population would need to change in such a way that communicating through miles of planet becomes our most practical option.

For example, nuclear/EMP attacks kill all the comm satellites and force what's left of humanity deep underground...where luckily some superpower or three has tucked away big particle accelerators in addition to MREs.

Or perhaps off-planet, trying to send messages to mining operators, or through asteroid fields...work with me here.
