5G has been called "an investment opportunity of a life time". Also up to 100 times faster than 4G. Will 5G live up to the hype?

3G took over from 2G - it was going to be amazing, wonderful, so FAST and it was until 

4G took over from 3G - it was going to be amazing, wonderful, so FAST and it was until 

5G took over from 4G - and so it will go on an on on and on, in 2 years 5G will be the ABSOLUTE, in 5 years it will be yesterdays crappy slow technology.

We are in a depression, with 20% unemployment, just 5% less than the 25% unemployment of the 1930s. Lots of people are jobless, and those who have money are not going to spend as freely as they did before. 5G is not needed by most people since what they have right now is good enough. If people are charged more for 5G, then it will flop.

Is there any kind of timeline for when 5G will actually be widespread?

I will believe it if I see it but the mobile phone industry has a history of not giving what it promised. I would love if what the T-Mobile employees say is true and I can use it to replace the cable company for high speed internet at home. 

I'm not convinced, at least yet. While I'm sure the technology can be good, the way the carriers have rolled it out, is atrocious. AT&T has already been misleading customers with their "5GE" network, which is basically an advanced version of 4G LTE. Verizon has seemed to have half-assed their 5G home Internet rollout in Sacramento, CA which is the nearest city to me that has some 5G network connectivity.

That sounds like a lot of hype.

Hard to say.  It has a lot of potential but its range is much shorter which means telecommunication companies have to add a lot of cell towers/transmitters to properly cover an area.  I hope its potential is there and it gives existing cable companies some real competition which is sadly lacking.

Youtube does not constitute 'peer reviewed' in the scientific community's meaning of the phrase.

Let's put it this way...I often just turn off my WiFi on my cell phone because the 5G I'm getting is fast enough for any streaming that I'll be doing.

If you research it, you'll find that 5G is very dangerous even to humans as the signal it transmits is RF radiation. There are hundreds of peer reviewed scientific studies linking RF Radiation to DNA damage and cancer. 

So if you want the life expectancy of homo sapiens to decrease, I would recommend using it. 

nothing is an "investment opportunity of a lifetime" if everyone else already knows about it. you could probably model this after the first modernized land line trends with many competitors building outward infrastructure but eventually merging or going bankrupt until there were only 2-5 companies left. the ccp company that everybody in America hates currently has the best chances of being the winner in 5g infrastructure. i don't know who will be 5g network operators (probably att and comcast and etc).

i feel more like 5g is like modern CPU speeds. you're going to go a decade or more where increase in speed/bandwidth become largely irrelevant to all but niche users (data intensive companies and gamer enthusiasts). the focus then becomes, far less on increasing speed, than on reducing energy cost, improving equipment lifetime, and reducing network operator costs rather than increasing data speeds.
