Neutrinos don’t need to go around the earth, so in theory you have a pi/2 advantage over an EM signal when sending to an antipodal location, for instance. In practice of course, throughput is utterly horrible for the reason you indicate.

Latency would also be degraded by the interaction property. The probability that you detect the first packet of neutrinos is extremely low.

All you need is a couple bits, but yeah, making sure it’s the neutrino your buddy sent and not some other one is where it gets complicated.
I think neutrino detectors capture at best something like 10 neutrinos per year or so, so the throughput would be severely limited.
This assumes that neutrinos aren't slowed by a dense medium as light is.
That's a maybe. Still, good point.

We already fire neutrino beams through the Earth's crust, and they travel at the speed of light, and the core isn't that much more dense.
