Multiple people here seem to be confused by “10G” thinking cellular data, but this is not that. It is an improvement of fiber optic home internet which resulted in 10-gigabit download speeds:

The deployment of 10G broadband is based on the world's leading 50G PON solution. By upgrading the underlying architecture of the optical fiber access network, the single-user bandwidth is upgraded from the traditional gigabit level to the 10,000-megabit level, and the network delay is compressed to the millisecond level.

Most current residential networks being built in the US support 2GiB (250MB)/S on a good day. That's about enough to saturate most disk drives, meaning of your were writing or reading from a hard disk, the hardware would likely be the bottleneck and not the network.

At 10G speeds, most M.2 SSDs would be saturated. So there's literally no difference (assuming the server can supply the full 10GiB connection), between accessing data over the network and accessing it from a local M.2 drive (ignoring latency of course).

That's actually kinda wild over any distance that isn't just LAN fiber. You can get 25GiB within an office pretty easily with high end switches that have 25GiB ports.

The only people getting even close to this in the US are commercial customers that are leasing a whole dedicated fiber on a back haul network like Zayo or from the Department of Transportation (they pull a ton of dark fiber on highway projects)
