You can push gigabit speeds through coaxial connections, easily. Why aren't they doing it? Money.
8K TVs arriving in couple years...still not many 4K content out there, but it'll surely drive demand for more bandwidth. What we used to do everyday is going to require 16x more bandwidth (from 1080p30 to 8K30). People are broadcasting themselves, too. Imagine the future data traffic going both inbound and outbound. Watching YouTube on the phone/tablet/computer while streaming 8K netflix on the TV...it's really growing exponentially. ISPs will be urged to steal competitor's loyal customers, and providing better service at affordable price is the smart way.

And how many TV shows are actively supporting beyond 1080p today? 4K screens aren't new, they've been around for a while, but the commercial industry rarely taps into 1080p and almost never, unless it's a nature channel or something from like National Geography, pushes up to 4K. You claim it'll drive the demand for more bandwidth. That didn't happen when 4K screens came out! What makes you think it'll force anyone's hand once that resolution grows higher?

And in any case, coaxial can handle 500/500 connections all day long, so the bandwidth is there, it's merely a matter of getting the ISPs to provide that bandwidth. If anything, all they'll do is provide a new top tier for double the available bandwidth and... everyone else will stay the same. That's all they ever do and all they ever have done in the past.

Until the speed of light through whatever medium is used for telecommunications is insignificantly slower than speed of light through a vaccum, there will be significant room for improvement.

I have no idea how to make a practical spacecraft that could travel near the speed of light, but until there is such a craft, there will be significant room for the improvement of spacecraft velocity. Similar premise.

Someone mentioned light not being able to go any faster than it does through glass fiber, thus there there being no room for improvements in latency in that regard.

I point out that the "speed of light" varies depending on the medium it travels through and use a hollow fiber (where light is mostly traveling through air) as an example of a way to transmit light at much closer to it's maximum speed.

That's the sum of the details relevant to my point.

If you want to explain why we can't maintain adequate signal strength through long runs of hollow fibers, go right ahead, but even if you describe it as a virtual impossibility (and I'll even take you at your word), it's still completely beside the point.

500/500 to where? To a node on your street?

Many people are still on multi-drop coax networks. 1000/1000 is only enough for a tenth of that or less due to other users on the network. Upstream is also heavily limited by the capability of the DCE to transmit over the long runs back to the node.

HP-UX. I came, I saw, I was sad it would not run on my X86 box.

Er...what?!

The demand for data transmission is utterly staggering, that's your real world practical application. A single fiber holds orders of magnitude more data than a coax conductor, at much lower latency over much, much, MUCH longer distances. Where are you getting these claims from?

Whats the point when everything is capped/throttled? Ive run through my 1tb cap 2 months running. I love how comcast used to think 300GB was a realistic cap. WE ARE A 4 PERSON HOUSEHOLD 1TB IS NOT ACCEPTABLE. On top of that every morning between 2am and 4am my speeds are throttled from 350mb/s to 20mb/s. Comcast blames high usage in my area. ITS 4AM ON A WEEKDAY IN A TOWN WHOS AVERAGE AGE IS 65Y/O, WHO THE **** IS USING ENOUGH BANDWITH TO THROTTLE A NEIBORHOOD, NO ONE, THATS WHO CRAPCAST! ........ sorry for getting heated.

Top it off its symmetric, none of that asymmetric rubbish that docsis is... (100/10 in my case, pfff....)

Are... you not aware that standards like 400gbps and 1tbps exist?

The backbone of the internet is faaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaar beyond whatever petty speeds you can buy.

Clearly he isn't. Keep in mind, that 400Gb/s is for ONE CHANNEL. A typical fiber might use, say, 40. Or more.
