In quantum mechanics, bosons are (often massless) force carrying particles like photons or gluons. Fermions are the massive matter particles, such as electrons or quarks.

So, while I’ve never heard this saying before, I assume it’s meaning is that massless particles like photons are best for carrying information around (rather than electrons we are using in circuits today), while the electrons are best for carrying state, like in a switch.

Note, that in networking we have already made that transition by using fiber optics, rather than electric wire to transfer information over longer distances.

And radio! We use lots of radio as well.

I wonder what the longest information carrying electric wire is? They used to cross oceans, but not anymore. There are loads of DSL twisted pairs and co-ax cables in the "last mile" that maybe go 5km max. In rural areas maybe up to 50km with repeaters?

Is there something in between? Some old buried copper trunk cable between two university campuses or something like that?

Depending on your definition of wire, probably the earth. The first telegraph systems used the earth (or sea water can't remember) as the return path.
