(or even Ethernet)

Technically, those 100+ Gbps fiber LAN/WAN connections used in data centers are also Ethernet, just not twisted pair.

That said recently I was in a retail store and saw “Cat8” cables for sale that advertised support for 40 Gbps copper ethernet! I wonder if any hardware to support that will ever be released. It is a real standard, approved way back in 2016: https://en.wikipedia.org/wiki/100_Gigabit_Ethernet#40GBASE-T

I have symmetrical 10 Gbps at home ($30/mo) and I’ll agree. When it’s nice when you have big updates, for most households 1 Gbps is going to be just fine. As you say, the vast majority of users are bottlenecked by Wi-Fi.

The bigger crime are all the asymmetrical connections that people on technologies like Cable TV networks have, where you get 1-2 Gbps down but only something tiny like 50 Mbps up. This results in crappy video calls, makes off-site/remote backups unfeasible, means you can’t host anything at home, etc.

Most residential fiber globally currently is GPON with a 1-2 Gbps shared line using passive optical splitters, split up to 32 ways. Raising that shared line to 50 Gbps is a great upgrade.
