Fine, 99% of China "landmass" does not have 50G. 100% of the US does not have 10G. The fact that in NYC, the richest city in the history of cities, most buildings still only have access to cable from a single provider is absolutely ridiculous. Urban centers is what is worth comparison here, and the US falls massively behind.
Very untrue. There are several providers in the US which offer 10Gbit services. Many more offer 2-5Gbit services pretty broadly. I've got friends in Kansas City with 40Gbit residential service. Sonic also offers 10Gbit in California.
Not all landmass because most of Tibet/Xinjiang empty, but ~100% wireless coverage east of Heihe–Tengchong line where ~95% of population are. Including Tibet/Xinjiang remote areas, ~95%+ of administered population areas down to village level where poor farmers have access to 5g AND fiber hookup option by now.
Building infra and networking gear is cheap in society that knows how to build and carriers are required to install in administered villages even if it's not profitable. Fiber adoption rate actually higher among rice farmers because they get subsidies, 1Gbps gigabyte fiber for cost of 200 Mbps in city and because bunch of villages got hooked up in last 10 years - they skipped straight to fiber which was bundled with road/power buildout.
Meanwhile US so dysfunctional / can't brute force rural fiber, need to literally invent SpaceX to plug gap. Which TBH is good copium.
