Nah, I'll wait for 6G!
It has been at least a decade since I actually worried about the specs of anything tech that I've bought. OK, in fact the last time that I built a new desktop PC I did take the time to futureproof it to a reasonable degree, but even then it was a couple of years behind whatever was new and shiny. I'm confident that as long as I can add more RAM, more drive space, or the inevitable power supply it will last me at least a decade. I'm not a gamer so my needs have become fairly stable.
Beyond that though, if I need something I buy what fits the budget and it seems to work just fine. Cel phones, routers, printers... pretty much any mid-range off-the shelf brand name will do a fine job without a lot of time comparing specs.
That's the challenge for the guys flogging 5G: 4G is mostly perfectly fine, and the complaints are seldom about speed or capacity, they're about areas with crappy signal, or about the extortionate prices being charged. (I speak as a Canadian who just got a new, better deal on wireless - $50 a month which includes a whole 4 gigs of data. Woohhoo! I can even update my podcasts once in a while without hitting the data cap!)
For me the killer sales pitch wouldn't be 5G, it would a battery life of more than one slightly short day. It would be OS updates for more than twelve months. And OS updates that don't break what I using now. I'd actually pay a bonus if it could be guaranteed that the basic software on my phone didn't change from year to year.
From an end user standpoint technology is pretty much mature and unchanging. You might be able to sell some bells and whistles, but a laptop or a cel phone or a router has reached the point where it's an appliance like a toaster or kettle. And no-one reads the specs on a toaster - either the bread turns brown, or it doesn't.
Trying to convince people that 5G is superior to 4G is about the same as trying to make them believe that the AC power from your wall socket is better than what comes of of your neighbours'.
