The physics is not conducive to improving the situation a lot.

There's probably $1.5 billion in the ground already in neutrino detectors; the total combined detector bit rate is pretty poor. One experiment looking at neutrinos coming off the Fermilab accelerator had 473 million accelerator pulses with under 1.1 million detected neutrinos.

Note that each pulse was probably millions or even billions of neutrinos, so the detection rate was even worse than you'd think. I saw a statistic that every second, 50 trillion neutrinos pass through your body. And the number that will interact is well into the single digits.
