What does this mean? Something beyond video? VR?
My instinct is that there are diminishing returns past a certain point. We're certainly not there yet, but once cellular networks allow you to stream high-definition VR content and upload data at the same rate, it seems like there's nothing more that additional bandwidth could add.
I see it as a philosophical issue... bandwidth is for the transmission of information, and there's only so much information that a human being can receive and provide at a given moment. At some point you're running up against the maximum bandwidth of the human user.
Well there is this famous quote "I think there is a world market for maybe five computers." from 1943 and it turned out to be very wrong.
"High-definition VR content" isn't the same as "indistinguishable from reality". When movies were first introduced to theaters, with small frames per second rates, without color and without any sound on the medium itself, people were quite stunned and e.g. took cover when a the movie showed a train approaching at high speeds. Nowadays it seems primitive to us from a technological standpoint.
There is a trend that some people don't accept lossy audio encoding. Maybe one day, videos will get a same trend and people want lossless videos, in full 360 degree VR, intensity resolution beyond perceptual limits and constantly high enough angular resolution for your eyes to foveate any area of the screen and see no pixels. That's quite a huge amount of data to transmit. Add in buffering so that you can seek, etc.
As for genuinely new forms of media, I could think of some: full-body experiences with feeling of touch, smell, etc either live or recorded possibly professional in a studio or just you sharing your last vacation to venice.
Taking it further: uploading your consciousness to a body which is a large distance away, making physical travel of humans mostly obsolete: Maybe one day we can represent the brains of human individuals as data and send it with light speed around the earth and throughout space.
It's like Netflix versus cable television - you can push the equivalent of hundreds of 1080p streams through a broadcast cable television, but attempting to push on-demand IP packets to an equivalent number of subscribers would bog down horrifically if they even attempted to stream a single show (let alone how you have cable tuners that can tune multiple shows at once).
What you need there is something much more akin to broadcast television - either a digital OTA video broadcast (good ol' digital television), or a microcell using multicast to broadcast a stream to any interested party.
(of course your phone probably doesn't have a DTV tuner, but when a RTL-SDR dongle is like $20, you should probably be asking why your phone isn't integrating that functionality. These days they don't even have FM tuners on phones anymore... despite the fact that in virtually all cases those are already built into the cellular chipset. IP-based singlecast is not a good paradigm for a lot of the use-cases that people come up with, it's just that it's the most profitable one for carriers, so it's the only one they'll support.)
Of course, this could also be accomplished with DTV tuners, but there's a much higher probability of users having a 5G chipset on their phone than having a DTV tuner capable of tuning to multiple channels and an antenna.
It's the same as what the app is currently doing, just with multicast groups instead of singlecast. And by doing so, you reduce the network load by N/M, where N is the number of users and M is the number of streams each user runs on average.
Don't get me wrong, I understand that this probably isn't currently implemented, but that's the kind of thing we should be looking at, before we decide to screw up weather forecasting and radioastronomy so that you can see your NAAAYYSSSCARR.
Even 5G is going to get eaten up under certain types of load, so it makes much more sense to look at ways to reduce traffic, the easiest of which is broadcasting rather than singlecast.
This isn't the place for cheap comments like that.
Even if you have a point ideologically speaking we live in the real world where consumer money talks louder than forum comments. 5G is coming whether we like it or not because of people wanting to stream data for entertainment.
Personally, I used my home gigabit extensively the first few months... but a year later I frequently find myself still tethered to my cellphone's 4G plan. It doesn't make a difference except once in a blue moon when I want to download something big.
