No one needs 10 Gb today, or the foreseeable future beyond 2030
As TRT says, what do you need it for? Even if you want multiple 4K streams like the one guy did, you won't get much above 100 Mb, let alone a gig - Netflix is using 15.6 Mbps for delivering their 4K streams. You must have a lot of TVs if a gigabit isn't enough for 4K streaming, let alone 10 gigabits!
The primary driver for faster broadband has been richer input to our senses. We went from text based content like BBSes to early web pages with small pictures to illegally sharing MP3s to rich web pages with big pictures to early Youtube flash videos to DVD quality Netflix to live HD streaming and live 4K streaming is around the corner.
Once we get there, the drivers for faster broadband run out of gas. Even if (and its a big if) we go to 8K and maybe a higher frame rate we still don't need a gigabit unless you need that to a dozen TVs simultaneously. The bureaucrats saying we need 10 gigabit by 2030 are simply extrapolating from past growth in broadband speeds, as if demand will continue for faster and faster broadband. It won't, because the driver of demand for faster broadband speeds runs out of gas as it catches up with supporting our most dense sensory input, 4K streaming video.
If you extrapolated the trend in cell phone size from phones like the RAZR in 2005 to 2015 where screens over 5" are very popular, you might conclude we will be carrying phones the size of an iPad Pro by 2025...
Note I'm just talking about speed to your house - the backbones and ISPs will need to handle more, as more and more people stream richer video. But even that will level off, it will just take longer until almost everyone is streaming all their video instead of watching 'traditional' broadcast TV.
