5G seems like a big bait and switch to me. It looks like an antiregulatory Last Mile play - it does best between stationary objects. It has really shitty penetration. It requires proprietary switching gear (unless you believe in fairies). If you were looking to have your cellular provider grind cable companies into the dust, 5G is exactly the play.

But it's being sold as "yer fone gun be phaaaast" and it's like "bitch you're watching 1080p Youtube videos at six inches across WTF do you care."

Picture-perfect mmWave 5G will give you 2gb/s. 802.11n will give you 300mb/ss. There is exactly no one who wishes their wifi were faster except insane audio video editor nerds such as myself and we're sitting here wishing M.2 were a little faster. M.2? 3.5gb/s. What, I'm going to edit 8k ProRes off the cloud now? When I built the birth center the local Avaya nerds tried real hard to get us to put in CAT6 wiring instead of CAT5e. I said "I'm running VoIP. What exactly is the use-case where I saturate my CAT5e?" Their response was "uhm... real-time viewing of diagnostic ultrasound over LAN?" And I mean... I've got a hot network card with four CAT5 connectors on it talking to a hot NAS with four CAT5 connectors on it and everything's all ganged from one end to the other and my hot-shit i9 can't saturate that connection anyway.

There's no use-case for 5G that isn't "giant telecom too lazy to last-mile the fiber." But for some dumb reason they're putting it in cell phones. Probably so they can make you pay for it.
