We are lind of hitting the limits with it, 5g and mm waves are attenuated by air , foliage and buildings, there must be some better way.
I think its the neutrino can be sent in three flavors at different speeds, can be sent directly through the earth at nearly the speed of light, much faster then fibers or RF from satellites. Maybe we arent seeing aliens because they used RF in the beginning then after 300 years they switched. Entangled pairs dont seem to work because you cant send faster then light info through them.
So whats next? 6g? I hear that gives you not only cancer and corona but also genital warts. gross.
