#2>5G would enable doctors to perform surgery remotely from across the country
I never, ever understood that argument; I simply can't imagine a hospital relying on a cellular network for such sensitive work.

#3Looking back I realized it felt similar hearing about 5G all the time just as it feels hearing about AI now.

Odd take, the 5G hype was talking about devices that _might_ exist in the future and _might_ solve problems. I have used AI (or ML at least) 4 times today to solve problems. One was hype and I might use, the other is in my hands and real.

Maybe the argument was more for government officials, not for people like you.

#6In my city 5G at the current provider is almost useless since it covers only the city center. At least, my 5G plan also allows using 4G.

#7It's a bit of a myth of the modern age that desire is unlimited. I think this is wrong. At some point our desire can be sated.
Eg, I'm pretty sure Bill Gates or Elon Musk don't buy the newest, latest phone that comes out every single time. Because at some point you find something that works well enough, and just thinking of using something else involves effort. Even if V2 is theoretically faster or has more RAM, maybe you have no need for that yet.
As tech improves, this happens more and more often. Back in the time of 4MB RAM, memory was an ever constant worry and constraint. Today I'm at the point where I only think about RAM or disk space is when something goes nuts and fills up the available space, otherwise it's just not an issue, and I just don't think of upgrading.
I think 5G is pretty much there. After having smooth, quality playback on youtube on my phone, my needs are fully sated. There's just nothing I need that requires downloading stuff to my phone any faster, and in fact it's been a long time since I last thought about how quickly my phone downloads stuff.

#8All the BS hype about 5G was a red flag for me. They were always showing how doctors could operate on people in far away places (never mentioning the fact that the people in the far away places probably have no health care) and it is also all supposed to lead to everything from energy efficiency to higher efficiency.
But all I get is a higher phone bill and no option to opt out of a 5G plan even though I turn it off on my phone.
And what did we probably really get? More surveillance. You do know, don't you, that these mmWave can pinpoint you and your activity with an ever increasing exactness that should concern all of us.

Re: The Disappointment of 5G
#9Ignoring all the hype and BS, all the cell infrastructure really comes down to a battle between user bandwidth needs and available spectrum (multiplied by spectral efficiency and density of towers). Get this wrong and customer service tanks as cell sites get congestied.
There are virtually no new applications enabled IMO with 5G speeds vs LTE speeds/latency, assuming they are both not congested. 100mbit/sec LTE with 20-30ms latency is fine for nearly everything; gigabit with 5ms latency on 5G doesn't really change much, at least for the next few years.
5G NR (the access layer of 5G) isn't hugely more spectrum efficient than LTE on a bitz/hz basis, at least on a downstream basis where the most demand is (upstream is really important too though, especially for TCP, I'm not discounting that). [1].
We are getting diminishing returns on spectrum efficiency. Which means more and more spectrum required to keep up with demands, which is really what 5G enables (more channel bonding, much wider channels). However, we are totally running out of spectrum to allocate to mobile services. The spectrum that is available in large quantities is extremely high frequency and can't really penetrate walls (it will even struggle with rain).
So long term the only thing that carriers can do is densify their cell sites, which is extremely expensive from a capex perspective. Some carriers have realised this, some haven't (or don't have the funds to do it). In the UK 3UK is doing it; with thousands of planning applications to add new sites (with huge NIMBY backlash everywhere).

What does this tell us about government officials?
