What would they use it for, though? The advantages of 5G are pretty much low latency and high bandwidth. What in everyone's life needs low latency and high bandwidth? Fortnite?
I got serious about it when I put the network in here. Since my NAS can bond four gigabit links, I gave it four gigabit links. And to make that worthwhile I put in a network card in my "can't buy a faster one" pro tools computer that would bond two gigabit links. Only to discover that my can't buy a faster one PC with 12 cores and M.2 drives literally could not write faster than a gigabit link.
You can get fiber channel up to 5G speeds. Faster than. I've got 10G fiber between two switches at the birth center. Why? Because I can (see "dev perspective"). And I can look at the metrics and see that there's nothing on my network, and no network devices, that can so much as tick it over and I've got a couple 4K cameras.
When I put in the network I took a bid from a datacom firm that really wanted me to put in 10gigE. I figured i'd be dandy with gigabit. No, no, they said. You might really regret not having 10gig when you "upgrade." Upgrade to what? I said.
Yeah. If I need to fling high resolution medical imaging from office to office without lag, I might saturate gigabit. But for the rest of the world? That mostly wants to watch Yankees games on their phones? Yer talkin' 8MBPS for 1080p H264.
